+ <gnu_srs1> teythoon: is the Hurd boot now fully init compatible? I would
+ like to try to boot with a ported openrc in a sandbox kvm:P
+
+
+### IRC, freenode, #hurd, 2014-01-12
+
+ <teythoon> gnu_srs1: yes, go ahead
+ <teythoon> gnu_srs1: you'll have to switch to sysvinit first
+ <teythoon> for that, you need patched sysvinit packages
+
+ <gnu_srs> teythoon: do you mean the parches in #721917?
+ <teythoon> gnu_srs: yes, mostly, but there is one final patch missing
+ <gg0> uploading patched sysvinit to debian-ports? (or braunr's or
+ teythoon's repos)
+ <teythoon> gg0, gnu_srs: they are actually here
+ http://teythoon.cryptobitch.de/gsoc/heap/debian/ but outdated
+ <gnu_srs> teythoon: if the sysvinit patches are outdated, can you update
+ them please? and provide a package for upload to -ports (as gg0 proposed)
+ <teythoon> gnu_srs: i will
+ <gnu_srs> tks:)
+
+
+### IRC, freenode, #hurd, 2014-01-13
+
+ <teythoon> gnu_srs: i updated the sysvinit patches
+ <teythoon> gnu_srs: for your convenience, here are packages:
+ http://darnassus.sceen.net/~teythoon/heap/sysvinit/
+ <teythoon> gnu_srs: you have to install the sysvinit-core package first,
+ then the others
+ <teythoon> to switch to sysvinit, do update-alternatives --config runsystem
+ and select runsystem.sysv
+ <teythoon> then, do reboot-hurd and hope for the best ;)
+
+ <gnu_srs> teythoon: thanks, will try soon. Are you submitting the updated
+ patches to #721917 too?
+ <teythoon> gnu_srs: i already did
+ <gnu_srs> good;-)
+ <gnu_srs> teythoon: rebooted with sysv:http://paste.debian.net/75925/
+ <teythoon> gnu_srs: please, whenever you run into a problem, give more
+ context
+ <teythoon> which file are you talking about ?
+ <teythoon> also, as the postinst script advised you, you need to use
+ {halt,reboot}-hurd *whenever* you switch the runsystem
+ <teythoon> not doing so wont do any harm, but it wont work
+ <teythoon> shutdown: /run/initctl: No such file or directory <-- that's
+ what happens if you run reboot (=reboot-sysv) w/o sysvinit being run
+ <teythoon> if you don't get a getty on the console, check /etc/inittab
+ <gnu_srs> I did note see a message from any posinst script about
+ {halt,reboot}-hurd, only LC* related messages
+ <gnu_srs> A I missed it: You must use halt-hurd or reboot-hurd to halt or
+ reboot the
+ <gnu_srs> system whenever you change the runsystem.
+ <gnu_srs> I don't see anything suspicious in /etc/inittab,
+ eg. 1:2345:respawn:/sbin/getty 38400 tty1 is there
+ <teythoon> 7:2345:respawn:/sbin/getty 38400 console
+ <teythoon> then, you'll get a getty on the mach console, even if the
+ hurd-console does not start
+ <gnu_srs> teythoon: with 7:2345:respawn:/sbin/getty 38400 console in
+ /etc/inittab I get a (mach) console.
+ <gnu_srs> never seen that mentioned anywhere
+ <gnu_srs> anyway, the image is now booted with sysvinit. next to try will
+ be openrc:P
+ <teythoon> gnu_srs: you haven't heard of the inittab entry for the mach
+ console before b/c the inittab was not used before on the hurd
+ <teythoon> i should probably write that down in the wiki somewhere...
+ <youpi> shouldn't the upgrade of the sysvinit package do it too?
+ <youpi> (does it at least install a correct version on newer installs?)
+ <teythoon> it probably should / i'm not sure

+
+ <teythoon> gnu_srs: have you ported openrc already ?
+ <gnu_srs> I made it build (with temporary workarounds for PATH_MAX) but

+ boot
+ <teythoon> cool :)
+ <gg0> i guess not much different from http://paste.debian.net/plain/75893/
+ <gg0> (i didn't say it sucks but one can find it out by taking a look)
+ <gnu_srs> gg0: Have you talked to zigo in #openrc?. He has partial patches
+ (submitted to the debian repo), you do and me too.
+ <gnu_srs> Maybe we should align our work.
+ <gnu_srs> The file to make Hurd-specific is: init.sh.GNU (you start with
+ copy of the Linux version, I start from a copy of the BSD version).
+ <gnu_srs> BTW: I don't think fstabinfo is available for GNU/Hurd!

+
+ <gnu_srs> Hi, is these some simple way to find out the sequence of commands
+ executed during boot:
+ <gnu_srs> current using runsystem.gnu and with sysv-rc using runsystem.sysv
+ <gnu_srs> I need to edit on file of OpenRC before trying to boot with
+ it. (mainly mounting /run/*)
+ <gnu_srs> Is mount functional or is settrans .needed?
+
+
+## IRC, freenode, #hurd, 2014-01-16
+
+ <ArneBab> gnu_srs: you are adding OpenRC? cool!
+ <gnu_srs> ArneBab: Working on it, will try booting when my questions here
+ have been answered ;-)
+ <teythoon> gnu_srs: mount is functional enough to boot Debian/Hurd using
+ sysvinit
+ <teythoon> gnu_srs: you could add "set -x" to runsystem.*, or add "bash" to
+ just drop into a shell and examine the environment interactively
+ <gnu_srs> teythoon: Hi, is mount a wrapper on top of settrans ...?
+ <teythoon> yes
+ <gnu_srs> how to log the boot sequence, when booting the mach console is
+ cleared when the hurd console starts?
+ <teythoon> you could just disable the hurd console
+ <gnu_srs> and the kvm console does not have scrolling functionality
+ <teythoon> it's actually the mach console that lacks this
+ <gnu_srs> copying manually is cumbersome, even if all is readable
+ <teythoon> but as a workaround you can use kvm .... -curses and use xterms
+ backlog
+ <teythoon> and c&p works then :)
+ <gnu_srs> tks, I'll try with that:P
+
+
+## IRC, freenode, #hurd, 2014-01-17
+
+ <gnu_srs> BTW: zigo successfully booted openrc on Hurd, I haven't tried
+ yet,, you know things coming in between. He used my patches to create
+ updated ones:)
+ <gnu_srs> that version is now in experimental (I still have to operate away
+ all those PATH_MAX issues, and fins at least one sh file).
+ <teythoon> :/
+
+
+## IRC, freenode, #hurd, 2014-01-21
+
+ <gnu_srs> teythoon: I don't get a scrollable output when using -curses in
+ kvm, to be able to see all startup messages. Any other ideas?
+ <teythoon> gnu_srs: are you sure ? i just tested this, and it works nicely
+ for me
+ <teythoon> gnu_srs: that's how i created all the "screenshots" for my blog
+ posts
+ <gnu_srs> teythoon: kvm -m 1024 -net nic,model=rtl8139 -net
+ user,hostfwd=tcp::5564-:22 -curses -hda debian-hurd-20140115.img
+ <teythoon> ah, my bad
+ <teythoon> gnu_srs: try -nographic
+ <teythoon> oh, and maybe you need to add console=com0 to the gnumach
+ command line
+ <teythoon> b/c with -nographic, the first serial port is connected to qemus
+ stdio
+ <teythoon> sorry, i mixed this up
+ <gnu_srs> and how to add console=com0 to the qemu start oprtions? -kernel
+ and -append are Linux only
+ <teythoon> # grep console /etc/default/grub
+ <teythoon> GRUB_CMDLINE_GNUMACH="console=com0 --crash-debug"
+ <teythoon> and if you want grub on the serial port:
+ <teythoon> # grep serial /etc/default/grub
+ <teythoon> GRUB_TERMINAL=serial
+ <teythoon> GRUB_SERIAL_COMMAND="serial --speed=9600 --unit=0 --word=8
+ --parity=no --stop=1"
+ <gnu_srs> teythoon: with -nographic I don't get any output at all?
+ <teythoon> did you run update-grub ?
+ <gnu_srs> aha, will do
+ <gnu_srs> still no scrollbar with gnome-terminal, will try with xterm and
+ rxvt
+ <gnu_srs> it works: with rxvt, tks:-D
+ <teythoon> good :)
+ <teythoon> i found -nographic to be quite handy
+ <gnu_srs> in /etc/default/grub: GRUB_CMDLINE_LINUX_DEFAULT="quiet" and
+ GRUB_CMDLINE_LINUX="" #GRUB_DISABLE_LINUX_UUID=true
+ <gnu_srs> linux configuration parameters in a gnumach boot setup?
+ <teythoon> those won't be used
+ <teythoon> unless the grub scripts find a linux kernel in /boot
+ <teythoon> it's just the stock debian configuration file
+ <gnu_srs> nevertheless:-(
+ <teythoon> what ?
+ <gnu_srs> there could be OS-specific files: Linux, kFreeBSD, Hurd?
+ <teythoon> or, preferebly, one that works on every os ? like it is now ;)
+ <gnu_srs> OK, one that works on every OS, with a common part and
+ OS-specific parts?
+ <teythoon> that's how it is now
+ <teythoon> stuff with LINUX in it is used for linux
+ <teythoon> stuff with GNUMACH in it is used for gnumach

+## IRC, freenode, #hurd, 2014-01-22
+
+ <ArneBab> I think with that you are doing the most useful thing to avoid
+ OpenRC: If it provides almost the same as systemd and runs on the Hurd,
+ then there is no technical reason for using systemd, but many against it.
+ <ArneBab> s/avoid OpenRC/avoid systemd/
+ <ArneBab> (gah, brain is jumbled)
+ <Shentino> I hate systemd because it monopolizes cgroups
+ <Shentino> which is SUPPOSED to be a generic interface open to anyone
+ <Shentino> I do not want an unholy alliance in a kernel-user api
+ <azeem_> ArneBab: the openrc maintainer will take care it will get
+ communicated
+ <azeem_> ArneBab: also, not sure what you mean about systemd, the question
+ isn't so much between openrc vs. systemd, but upstart vs. systemd
+ <azeem_> at least for the Technical Committee decision, none of the
+ tech-ctte members seems to consider openrc as n realistic contender
+ <azeem_> s/as n/as a/
+ <gnu_srs> azeem_: seem like it is so:-(
+ <gnu_srs> maybe in a future, if openrc gets some attention and developers,
+ it could become a one-for-all solution;-)
+ <teythoon> gnu_srs: nice :)
+ <teythoon> ignore the proc related message
+ <teythoon> gnu_srs: there is no way to associate the segfault with a
+ process for me, can you shed some light on which process dies ?
+ <teythoon> as for df complaining, you could fix this up like youpi did:
+ <teythoon> grep ln /etc/hurd/rc
+ <teythoon> ln -s /proc/mounts /var/run/mtab
+ <teythoon> the proper way is to fix our libc of course
+ <gnu_srs> teythoon: I was just coping the boot messages, I don't know
+ either which process segfaults
+ <teythoon> hm, maybe you can make openrc more verbose about what it starts
+ <gnu_srs> All I wrote earlier was from sysv-rc
+ <teythoon> ah
+ <teythoon> i've never seen that then
+ <ArneBab> azeem_: actually I think OpenRC is the only sane choice: It is
+ the only choice which supports other kernels.
+ <ArneBab> Shentino: I can’t stand systemd, because it establishes a tight
+ control over the init process by encouraging developers to add
+ dependencies to libraries which are so tightly coupled with others, that
+ they cannot be adapted without affecting the whole system.
+ <ArneBab> Shentino: But I wrote about that in much more details:
+ http://draketo.de/light/english/top-5-systemd-troubles TL;DR:
+ distributions become completely dependent on a small group and they throw
+ away the skills their maintainers already have (shell scripting)
+ <ArneBab> And systemd is Linux-only…
+ <ArneBab> …with no intention of changing that.
+ <braunr> why would debian strive to support other kernels ?
+ <braunr> instead of other kernels adjusting ?
+ <braunr> if posix introduces new apis, are we going to say no, or are we
+ going to try and support them ?
+ <braunr> the issue of multi-kernel support is completely irrelevant
+ <braunr> what you're saying about tight coupling is actually the only real
+ issue of systemd
+ <ArneBab> braunr: I see a difference between providing a stable API which
+ others can easily replicate and a running target with no intention to
+ become cross-kernel usable (my experience with udev suggests that they
+ won’t really try to keep anything stable for long).
+ <ArneBab> braunr: but the tight coupling is the main issue for me, too:
+ that creates a vulnerability for the free software community.
+ <braunr> no, the free software community doesn't risk much here
+ <braunr> it's a technical problem
+ <braunr> ok, yes, posix as a point of convergence is clearly not the same
+ as linux as an implementation that diverges
+ <braunr> agreed
+ <ArneBab> if the systemd people decide to go a certain direction which
+ makes it impossible to provide a certain feature while using their new
+ tech, then there is a problem.
+ <braunr> but it still implies we have to adapt
+ <braunr> from my point of view, multi-kernel distributions are a technical
+ heresy
+ <braunr> if you want something really efficient, you want it very well
+ integrated
+ <teythoon> i'm concerned by the linux kernel making up interfaces w/o
+ proper considerations
+ <ArneBab> braunr: in Gentoo we had all the hassle with /usr on a separate
+ partition. There are usecases for that, and Gentoo wanted to provide
+ them, but udev (now systemd) made that impossible.
+ <braunr> teythoon: yes i'm concerned about that too
+ <teythoon> we will never be able to implement the cgroup interface for
+ example b/c it is too badly designed
+ <braunr> badly ?
+ <braunr> it's system specific
+ <ArneBab> braunr: also the systemd folks could essentially hold Linus at
+ ransom: “We couple userspace tightly to implementation details in the
+ kernel, so when you break the implementation in a way which we don’t
+ like, you’ll break userspace in the worst possible way”
+ <braunr> it's very hard to design an interface without properly
+ understanding what it would internally imply in the implementation
+ <braunr> ArneBab: that's already the case
+ <teythoon> system specific in a way that it will be impossible to implement
+ on non-monolithic kernels
+ <braunr> teythoon: exactly
+ <braunr> they didn't think of that because they don't care
+ <braunr> and why would they ?
+ <braunr> it doesn't make the interface bad per se
+ <ArneBab> it is the case in systemd, but not in sysVinit
+ <braunr> well it is too
+ <braunr> but sysvint is less demanding
+ <braunr> again, the coupling is the problem
+ <ArneBab> yes
+ <braunr> systemd comes from people with other goals and interests
+ <ArneBab> I think everything I wrote comes down to that.
+ <braunr> they're very technical, very business oriented
+ <braunr> they want to get up to speed with competitors quickly
+ <braunr> they're not wrong in doing that
+ <braunr> it just helps understand why they get with such results
+ <ArneBab> A distribution would be foolish to let other people take over a
+ crucial part of the system when those other people have a track record of
+ coupling more and more parts of the system with their product.
+ <braunr> and i agree, i don't want it either
+ <braunr> but please, stop with the nonsense
+ <braunr> don't say openrc is the only sane one because it's the only
+ multikernel one
+ <braunr> personally, i consider that very argument almost insane itself
+ <braunr> considering distributions that are hardly used can really have any
+ weight in the decision is absurd
+ <ArneBab> openrc is the only sane one, because it keeps already aquired
+ skills useful.
+ <braunr> s/distributions/kernels/
+ <ArneBab> (that’s my opinion)
+ <braunr> we have to make progress
+ <braunr> the init system is clearly obsolete and lacking features
+ <braunr> so "acquired" skills here are irrelevant too
+ <braunr> if it takes acquiring new skills to operate a better init system,
+ i'm all for it
+ <braunr> after all, it makes a lot more sense to me than all those fancy
+ languages/technologies like C# and ruby that have gained so much
+ popularity in so little time
+ <ArneBab> If you can get a similarly good init system wiothut forcing
+ people to learn new skills, that’s a big win.
+ <braunr> you probably can't
+ <ArneBab> OpenRC is pretty close in features to systemd
+ <teythoon> err
+ <teythoon> not even close
+ <braunr> teythoon is right
+ <braunr> openrc is just sysvinit++
+ <teythoon> no
+ <teythoon> openrc replaces the sysv rc, not sysvinit
+ <braunr> ok
+ <teythoon> it complements it
+ <braunr> i wasn"'t being pedantic here
+ <teythoon> nicely in my opinion
+ <braunr> yes i like it too
+ <braunr> but i'm afraid it's not a complete solution
+ <ArneBab> I think I need to be more pedantic in what I say: A system-boot
+ with OpenRC is pretty close in features to a system-boot using systemd.
+ <braunr> on the other hand, when i see discussions about event driven
+ systems and handling of dependencies, it sounds like something like
+ openrc could do the job, and something else, system-specific, would
+ handle the rest
+ <braunr> ArneBab: i disagree
+ <teythoon> me too
+ <teythoon> ArneBab: have you actually used systemd?
+ <ArneBab> I have read about what it provides.
+ <ArneBab> My udev experience burned me pretty badly.
+ <braunr> udev is only one part
+ <braunr> but actually, coupling is both a problem and a great feature
+ <teythoon> yes
+ <braunr> it's precisely the integration of many services previously
+ organized in a very messy way that makes it better
+ <braunr> and cgroups, by accurately tracking resources, allow even better
+ control
+ <teythoon> heh, i watched lennarts recent talk about kdbus
+ <ArneBab> but it does so by pulling in more and more parts instead of
+ providing a clean interface which separate projects can use.
+ <braunr> again, the coupling is too tight
+ <braunr> it's hard to hook in between
+ <ArneBab> teythoon: I watched lennart troll a talk pretty badly…
+ <ArneBab> braunr: yes
+ <teythoon> he cites mach and hurd for having an nice ipc mechanism, and
+ linux lacking such a system
+ <braunr> haha
+ <braunr> i was expecting such comparisons :)
+ <ArneBab> that’s why he writes an init-system which does not run on the
+ Hurd…
+ <teythoon> ArneBab: that's trolling on your part ;)
+ <braunr> :)
+ <ArneBab> somehow yes…
+ <braunr> what i personally get out of this is that, in the end, proper
+ messaging at the kernel level is something people do want
+ <braunr> and if you make stuff like x use it, why not things like the
+ network stack and the file system
+ <teythoon> i wish the linux kernel would allow the kernel devs to write
+ nicer interfaces
+ <ArneBab> yes
+ <braunr> they're almost in the process of acknowledging the merits of
+ multiserver architectures :)
+ <teythoon> b/c they lack a proper ipc mechanism, they do stuff like ad-hoc
+ filesystem-based interfaces that are crappy to support on the hurd :-/
+ * ArneBab has been out of the loop for too long…
+ <braunr> teythoon: what file system do you consider "crappy to support on
+ the hurd" ?
+ <teythoon> braunr: cgroupfs in particular
+ <teythoon> not crappy, but impossible
+ <braunr> well, that's probably because we need realy resource containers
+ first
+ <braunr> real*
+ <teythoon> no, we'll never be able to implement the current interface
+ <braunr> i didn't study it as you did so i trust you
+ <teythoon> braunr:
+ http://teythoon.cryptobitch.de/posts/cgroupfs-is-as-cgroupy-as-it-gets/
+ <braunr> ok this would require proper support at the client side
+ <teythoon> yes
+ <braunr> i wouldn't say impossible but definitely not as clean as we would
+ want it
+ <braunr> far from it
+ <teythoon> how would you ever implement it w/o fixing the client
+ (i.e. fixing the interface first) ?
+ <braunr> the client would translate the request
+ <teythoon> magical write retries ?
+ <braunr> probably
+ <teythoon> uh
+ <braunr> clients are the only entities which know what their file
+ desctiptors refer to
+ <braunr> descriptors*
+ <teythoon> yes
+ <braunr> so writing such a request would make the client get a magic retry,
+ and use the proper rpc, passing the proper rights instead
+ <teythoon> yeah, i can see how that could work
+ <teythoon> but i'm not sure that we should go down this path ...
+ <braunr> we probably really do'nt want to :)
+ <braunr> i'd personally be fine if debian would allow two init systems
+ <teythoon> me too
+ <braunr> with the powerful linux-specific one still allowing sysvinit
+ scripts
+ <teythoon> in particular b/c the sysvinit scripts are already there
+ <braunr> from what i've read, they all provide some decent backward
+ compatibility with sysvinit
+ <teythoon> yes
+ <braunr> and i think we can count on the linux community to riot if,
+ assuming systemd was chosen, it becomes too hard to use and tweak
+ <braunr> again, these people want their software to be used
+ <braunr> so they'll probably manage something decent in the long run,
+ whatever is chosen
+ <braunr> i don't care much
+ <braunr> :)
+ <kilobug> AFAIK Debian is planning to let users chose the init system, the
+ discussion is only on what should be the main/default one; but I might
+ have misunderstood it
+ <braunr> that was one of the possibilities, yes
+ <braunr> maybe we could help the debate by agreeing on whether or not we
+ consider supporting ports is that important, as port maintainers,
+ considering we'll probably keep the ability to use sysvinit scripts
+ anyway
+ <braunr> and making that decision known
+ <teythoon> and stating that we consider openrc an worthwile incremental
+ improvement, whatever debian decides to do wrt to the default init system
+ <braunr> for example, yes
+ <braunr> we should discuss that with youpi and thomas
+ <braunr> tschwinge: ^
+ <braunr> when they have some time later :)

+ <gnu_srs> Good news, a successful boot of Hurd with OpenRC:
+ http://paste.debian.net/78119/ :-)
+ <gnu_srs> ramains to fix the false negative for checkpath -W
+ <gnu_srs> remains*
+ <braunr> not bad
+
+ <gnu_srs> teythoon: btw, the segfault happens when starting the bootlogd
+ service:
+ <gnu_srs> end_request: I/O error, dev 02:00, sector 0
+ <gnu_srs> Segmentation fault
+ <teythoon> gnu_srs: nice progress :)
+ <teythoon> i've never seen bootlogd crash like that, though i
+ <teythoon> i'm not sure it is installed
+ <gnu_srs> how can I check / ? it is mounted RW and even if cd to /run which
+ is on tmpfs, fsysopts --readonly fails:
+ <gnu_srs> :fsysopts: /: --readonly: Device or resource busy
+ <gnu_srs> I don't have bootlogd installed the segfault is at:
+ <gnu_srs> checkroot.sh: hwclock.sh mountdevsubfs.sh hostname.sh hdparm
+ keyboard-setup
+ <gnu_srs> called by /etc/rcS.d/S06checkroot.sh
+ <teythoon> you should probably create this directory that it fails to
+ create early in the boot process

+
+ <antrik> braunr: being Linux-only is *part* of the "tight coupling"
+ strategy of the systemd cabal
+ <antrik> of course you could implement all the Linux-specific interfaces on
+ other systems; as you could implement any other interfaces relied upon or
+ provided by systemd components...
+ <antrik> (this is in fact Lennart's favourit cop-out argument whenever
+ someone raises concern about this)
+ <antrik> the problem however is that such alternative implementations
+ usually have prohibitive costs
+ <braunr> yes i know
+ <antrik> (and Lennart knows that perfectly well... he doesn't exactly take
+ pains to conceal the fact that it's a cop-out)
+ <antrik> their whole point is to create a tightly integrated stack of
+ monopolistic components, giving a shit about any possible alternatives
+ <antrik> this does have an obvious appeal: it *significantly* reduces the
+ cost of innovation within their stack
+ <antrik> at the same time however it kills the traditional innovation
+ driver in the free software eco-system, which is competition among
+ interchangable components
+ <antrik> quite frankly, it makes little sense that other distributions are
+ embracing systemd in droves: the tight coupling pretty much turns them
+ all into Fedora look-alikes, questioning the point of their very
+ existence...
+ <zacts> what is dmd?
+ <antrik> as for Debian considering fringe kernels in their decision, I
+ think it makes *perfect* sense: the real value of Debian is precisely the
+ fact that it supports so many different things, making it a good base to
+ build upon
+ <antrik> (it's just unfortunate that many Debian developers do not realise
+ this, and instead try to compete with user-oriented distributions...)
+ <antrik> zacts: daemon managing daemon? yet another new init system...
+ <zacts> yeah
+ <zacts> didn't know if you have an opinion on it vs systemd
+ <zacts> and whether or not hurd will use it..
+ <antrik> hm... not sure whether I do ;-)
+ <braunr> antrik: one could argue an init system is hard to make
+ interchangeable without also making it quite poor in functionality
+ <antrik> the GNU system uses it, right? when using the GNU system with the
+ Hurd (as it's really meant to be), that would obviously mean using DMD
+ with Hurd. though I'm not sure whether anyone has actually tried that
+ combination ;-)
+ <braunr> just to make it clear, i'm totally not in favor of systemd
+ <braunr> i'm just trying to measure the value of an interchangeable init
+ system here
+ <braunr> value versus cost
+ <braunr> why is it bad to try to compete with user oriented distros ?
+ <antrik> braunr: I suspect most of the really good things about systemd
+ could be kept while making it somewhat more open at fairly little cost...
+ <antrik> braunr: because that's not Debian's strength -- and never will be
+ <antrik> trying to compete in this space too hard is bound to fail, at only
+ bears the risk of loosing the actual strengths
+ <braunr> antrik: sounds true
+ <antrik> hm... thinking about it, I'd say it actually makes more sense for
+ the init system to be distribution-specific than kernel-specific...
+ <braunr> that makes sense
+ <braunr> but systemd isn't just an init system
+ <antrik> it's really the distribution's job to create a well-integrated
+ system. and basically, that's what the systemd cabal is doing for
+ Fedora...
+ <antrik> it's just problematic that they have so much influence in
+ important upstream projects, that they are basically killing any chance
+ for others to integrate things in different ways
+ <braunr> antrik: agreed
+ <braunr> the tight coupling i refer to is about the init system and the
+ upstream projects you mention such as udev, acpid, console-kit, etc..
+ <antrik> yeah... and GNOME
+ <braunr> is it really that coupled now ?
+ <antrik> don't really know; but judging from remarks people make, it must
+ be pretty bad
+ <braunr> this reminds me of the talk on gnome 3 last year at fosdem
+ <braunr> it would have been hilarious if gnome wasn't such an important
+ project
+ <antrik> (specifically, GNOME is now pretty much tied to logind AIUI, which
+ is not entirely inseparable from systemd -- but again, the cost is
+ prohibitive...)
+ <teythoon> i don't get what all the hate here is about ...
+ <antrik> in fact, certain people used that as an argument why Debian must
+ switch to systemd as init, as they are already pretty much forced to use
+ various of the other coupled components anyways, and trying to decouple
+ them is too costly for Debian...
+ <braunr> teythoon: hate ? here ?
+ <teythoon> i mean they don't do this for fun, they actually provide
+ something of value, right ?
+ <braunr> some value
+ <antrik> teythoon: they?
+ <braunr> but they remove the kind of value that made free software evolve
+ the way it did, as antrik said
+ <teythoon> the evil cabal around systemd ;)
+ <antrik> I didn't say "evil"... not explicitly at least ;-)
+ <teythoon> then again, if you are runnign linux/gnome3 and plug in a second
+ monitor, that one is automatically activated
+ <braunr> yes, that's what they want to achieve
+ <teythoon> that's what they achieved
+ <braunr> i mean, they targetted that, it's not a side effect
+ <teythoon> and anyone not happy with how they did that can surely provide a
+ nicer solution ;)
+ <antrik> teythoon: as I said, there are clearly good aspects to what they
+ are doing -- but at the same time it's very dangerous to the free
+ software eco-system...
+ <braunr> teythoon: not easily
+ <teythoon> antrik: i don't buy that
+ <braunr> i do
+ <teythoon> braunr: yes, not easily. that is kind of the point, right ?
+ <braunr> pulling projects such as gnome into a category of kernel specific
+ applications is dangerous
+ <braunr> teythoon: well, considering who they are and the means they have,
+ they could have spent the time to do it right for everyone
+ <teythoon> maybe
+ <antrik> err... activating a second monitor is not in any way tied to
+ systemd or related compontents... I think you are talking about a second
+ seat
+ <teythoon> that's another killer feature they achieved, yes
+ <antrik> (which is nice, but quite frankly, a niche use case in my book...)
+ <teythoon> maybe you're not the typical user
+ <antrik> I'm not. but the *typical* user definitely doesn't care about
+ multi-seat
+ <teythoon> if you say so
+ <teythoon> antrik: when you say it's dangerous what 'they' are doing, what
+ do you mean exactly ?
+ <teythoon> dangerous for whom ?
+ <antrik> asides from schools in developing countries, who try everything to
+ save on IT costs, I really can't think of many users for multi-seat...
+ <teythoon> (maybe schools all around the world trying to cut down their
+ costs?)
+ <teythoon> or like everyone, here, a $30 dongle that gives you an extra
+ workstation, how awesome is that ?
+ <antrik> teythoon: see above: they are killing the ability to combine
+ interchangable components, which has always been a core asset of the free
+ software ecosystem
+ <teythoon> antrik: so gnome is going for systemd, and gnome loses the
+ ability to be used w/o systemd
+ <teythoon> why do you care ? how does this affect the whole ecosystem ?
+ <teythoon> i really don't get why everyone is getting so upset about this
+ <antrik> teythoon: who cares about a dongle giving an extra workstation?
+ the remaining users of workstations are either corporate -- who prefer
+ dedicated boxes for organisational reasons -- or gamers, who want all the
+ power to themselves...
+ <braunr> teythoon: well gnome is kind of one of the major destkop software
+ in the free software world
+ <antrik> s/one of//
+ <teythoon> antrik: you stated that you havent used gnome3, yet you have an
+ opinion how tightly it should be coupled with systemd or linux
+ <teythoon> people who haven't used systemd or upstart have an opinion about
+ which one should be preferred
+ <braunr> teythoon: why do you think people shouldn't think about systems as
+ a whole ?
+ <antrik> teythoon: actually, I am using it (for some value of "use") --
+ though in legacy mode, as my hardware can't run the new bling...
+ <braunr> in that case, people shouldn't be allowed to vote, because that
+ would require them to be politicians ..
+ <teythoon> it's okay to think about that
+ <braunr> i don't think it is
+ <antrik> teythoon: but seriously, whether *I* have used it is quite beside
+ the point. I have no illusions about being a niche user
+ <braunr> people don't need to use something to actually understand it
+ <teythoon> but i cannot stand all the whining lately in the free software
+ world...
+ <braunr> whining isn't fair
+ <braunr> i mean, the word
+ <teythoon> y ?
+ <braunr> it's a big problem and complaining to force a debate is important
+ <teythoon> yes, but "they" are solving problems, and everyone is
+ complaining for one reason or the other
+ <braunr> they are also creating problems
+ <braunr> and not everyone is complaining
+ <teythoon> as opposed to offering alternatives
+ <braunr> that's a major issue, a lot of people are favorable to these
+ changes
+ <teythoon> and if you don't like what "they" are building, you are free not
+ to use it, no ? that's a freedom too ;)
+ <braunr> no
+ <braunr> you aren't
+ <teythoon> what ?
+ <braunr> that's precisely the point
+ <braunr> you'll be de facto forced to use it if you want to keep using the
+ rest
+ <teythoon> i'm free not to use gnome3
+ <braunr> you won't be free from using linux if you want gnome3
+ <teythoon> what kind of argument is that ?
+ <braunr> i'm abusing the word freedom
+ <braunr> because it has no clear meaning in practice
+ <braunr> as antrik said, it's about interchangeability and portability
+ <braunr> and alternatives
+ <braunr> accepting the way systemd is designed is a major shift towards
+ making linux its own standard, away from the rest
+ <braunr> and the way it's done isn't thought to easily allow the
+ alternatives to keep up with the changes
+ <teythoon> we agreed the other day that they shouldn't create ad-hoc
+ interfaces like they do, yes
+ <braunr> well that's the whole point
+ <teythoon> you just talked "about the way systemd is designed"
+ <braunr> they could invest some more effort to make well designed
+ interfaces that allow changing both the dependencies and the services
+ provided
+ <teythoon> how is that related to bad interface design ?
+ <braunr> for me, it's almost a synonym
+ <braunr> and we discussed it
+ <teythoon> aren't tightness of coupling and quality of interfaces
+ completely orthogonal ?
+ <braunr> it is designed with a narrow set of apparently company directed
+ interested towards a single system, a single distribution even, and
+ nothing else
+ <braunr> no
+ <braunr> absolutely not, when it's about something that should be
+ interchangeable
+ <braunr> an interface that forces tight coupling is of low quality to me
+ <antrik> braunr: they claim it's not actually company-directed... and I
+ tend to believe them on *that* point TBH
+ <braunr> antrik: this would have been a valid reason at least
+ <antrik> teythoon: it's just not right that some people can no longer use
+ major pieces of free software just because a tiny but highly vocal cabal
+ decides to disrupt the whole ecosystem
+ <teythoon> what are you talking about ? you are free to use older versions
+ of the software
+ <braunr> i's not technically feasible
+ <braunr> or it would require forking to maintain
+ <braunr> again, it's the start of a rift
+ <teythoon> but, if the gnome people want to go into that direction, who are
+ you to say that they shouldn't ?? that's what i get the least about this
+ kind of argument...
+ <braunr> i'm part of the free software community
+ <braunr> more accurately, the free unix-like community
+ <teythoon> and you are actively developing gnome... ?
+ <braunr> if they want to get out of this community, they'll hurt it, and
+ themselves
+ <braunr> do you understand what a rift is ?
+ <teythoon> but that's their choice, no ?
+ <braunr> a major division ?
+ <braunr> so what ?
+ <braunr> it doesn't mean it's a good one
+ <teythoon> you pick the desktop environment you like next best and be done
+ with it ?
+ <braunr> it's almost public service at this point
+ <braunr> what if they all do the same thing ?
+ <teythoon> err
+ <teythoon> they don't
+ <braunr> you won't be free to do what you want because the technical
+ possibility will have disappeared
+ <braunr> kde might
+ <braunr> if only to compete with gnome
+ <teythoon> well, if you don't like hte direction a project is taking, you
+ fork it
+ <teythoon> that's what happened
+ <braunr> exactly ..
+ <teythoon> why the long faces ?
+ <braunr> forks increase complexity and reduce manpower
+ <braunr> fork == division
+ <braunr> forking in the free software community is normally a last resort
+ <teythoon> huh ? since when is this considered a bad thing ?
+ <braunr> it's not a bad thing per se
+ <braunr> it usually implies a bad situation
+ <teythoon> < braunr> fork == division
+ <teythoon> and division == rift
+ <braunr> think of these situations that were caused by stupid drama and
+ lead to the duplication of a lot of effort
+ <braunr> openbsd, eglibc, jenkins, to name a few
+ <teythoon> i don't
+ <teythoon> why would i ? i never created these forks
+ <braunr> it affects the community as a whole
+ <teythoon> but the people who did thought it was necessary
+ <braunr> the fact they could do it is good, the fact they had to do it
+ isn't
+ <braunr> they were usually forced by the situation
+ <braunr> and often by the stupidity of other people
+ <teythoon> someone forced someone else to fork a project ? with a gun or
+ something like this ?
+ <teythoon> i don't buy this ;)
+ <braunr> of course not ..
+ <braunr> eglibc was forced by the inability of drepper to accept a whole
+ class of patches
+ <braunr> openbsd because theo de raadt has some huge ego
+ <braunr> for jenkins, it was a licensing issue iirc
+ <braunr> nothing technical at all
+ <braunr> nothing in the interest of the community
+ <teythoon> err
+ <teythoon> it brings diversity
+ <braunr> no
+ <braunr> netbsd versus freebsd brings diversity
+ <teythoon> i thought that was a good thing
+ <braunr> openbsd was just agotistic crap
+ <braunr> ego*
+ <teythoon> if there is no diversity, why should stuff be interchangeable if
+ there are no alternatives?
+ <braunr> and netbsd and freebsd aren't exactly forks, they're both bsd
+ based but had different goals from the start
+ <braunr> that's not what i'm talking about
+ <braunr> eglibc isn't exactly a new libc
+ <braunr> it's glibc+the stuff that should have gone into it
+ <antrik> teythoon: the stuff the systemd cabal does builds on the work of
+ thousands of projects and people; yet they act as if the don't own anyone
+ anything, and it's fine to boot out large parts of the community whos
+ work they are building on
+ <braunr> iceweasel isn't a whole new firefox
+ <braunr> most often, alternatives aren't forks of one another
+ <braunr> if they are, they have diverged a lot
+ <teythoon> antrik: that is your interpretation, and i respectfully disagree
+ with it;)
+ <braunr> and usually have different goals
+ <braunr> that's diversity, and i'm very ok with it
+ <braunr> (being a hurd guy and all)
+ <braunr> but forking because of decisions that prevent alternatives is a
+ very bad reason to fork
+ <teythoon> again, who are you to tell a project (say gnome) what they
+ should do or not ?
+ <braunr> that question makes no sense
+ <braunr> we're trying to think objectively
+ <braunr> forget who we are
+ <braunr> think about what should be done
+ <teythoon> no such thing ;)
+ <braunr> ok well, in that case, i'm a very smart person who knows a lot of
+ things, and people had better do what i tell them ;p
+ <braunr> satisfied ? :)
+ <teythoon> yes
+ <teythoon> that's much better actually
+ <braunr> not really ..
+ <teythoon> it's more honest
+ <braunr> no it was sarcasm
+ <braunr> what was honest are the arguments i explained
+ <braunr> why care about who says them ?
+ <teythoon> i do
+ <antrik> teythoon: there is not much interpretation in there really. some
+ of their own statements are quite explicit...
+ <braunr> damn non scalable kernel ..
+ <teythoon> who is "their"? what statements ?
+ <braunr> teythoon: when building glibc, there are so many nodes to fake
+ that ext2fs+fakeroot allocate enough ports to starve kernel memory ...
+ <teythoon> if i were mr. gnome3 and you would tell me that i should cuddle
+ with systemd b/c that's bad for one reason or another, the first thing
+ i'd like to know is who is telling me that
+ <braunr> teythoon: why not solely consider the argument ?
+ <teythoon> braunr: yes, i can imagine fakeroot doing that
+ <antrik> teythoon: Lennart and his friends. not sure how much of these
+ statements I have seen written down -- part of it I heard myself from
+ their own mouths
+ <teythoon> braunr: b/c maybe i like to develop my project in the direction
+ i want
+ <braunr> that's unrelated
+ <teythoon> and if anyone disagrees, she may fork
+ <braunr> this is a debate
+ <teythoon> why ?
+ <teythoon> so now we are debating what i may develop or not ? you lost me
+ ;)
+ <braunr> a way to reach consensus
+ <braunr> many people are discussing so that projects like debian and gnome3
+ make the best decisions
+ <braunr> a naive way to explain it is that the result is the sum of what
+ everyone likes and how louds he speaks for it
+ <teythoon> sure but you are not a gnome developer, no ?
+ <braunr> no, but again, i'm a free software community member
+ <braunr> and this affects the whole community
+ <braunr> because gnome3 is a major software component used by a lot of
+ people
+ <braunr> well, gnome at least
+ <teythoon> so the gnome project needs to seek consensus with everyone of
+ the free software community ?
+ <braunr> no
+ <braunr> that would be unanimity
+ <teythoon> but wrt to the systemd integration ?
+ <braunr> siding with systemd is starting to get away from the free software
+ community
+ <braunr> or, by bringing a lot of people along, dividing it
+ <teythoon> that's your interpretation
+ <braunr> yes
+ <braunr> always
+ <braunr> you don't have to say it, we're not doing raw science here
+ <braunr> it's implicit
+ <teythoon> i think it's important to point that out and make it explicit
+ <braunr> you made it several times
+ <braunr> we got the point
+ <braunr> what matters in the current discussion is whether you agree or not
+ and why
+ <braunr> and this will be your interpretation too
+ <braunr> and we'll see if it's convincing
+ <braunr> but, from experience, i expect noone will be convinced ;p
+ <teythoon> ^^
+ <braunr> the issue is too tied with the core goals we have in mind
+ <teythoon> but why does it matter whether i agree or not
+ <teythoon> that's my point actually
+ <braunr> you seem to have a problem understanding the issue, i was trying
+ to convince you there is one
+ <braunr> so, if i want to achieve that, it matters
+ <teythoon> what core goals ?
+ <braunr> basic dialectic
+ <braunr> well, for example, for me, i want people to think of the system as
+ a whole
+ <braunr> i want something effective, technically very good, and that
+ respects user freedoms
+ <braunr> i also want alternatives, i won't explain why, let's say it's
+ obvious
+ <teythoon> i agree
+ <braunr> well, systemd people don't think of the system as a whole
+ <braunr> here, what i call "system" is very large
+ <braunr> it would almost equal society
+ <braunr> i understand why they do that
+ <braunr> they have the right to do that
+ <braunr> but then i could say i understand why people make proprietary
+ software, and they also have the right to do it, i still won't approve it
+ <braunr> it contradicts my personal goals, my personal view of how things
+ should be
+ <teythoon> i completely agree
+ <teythoon> but then again, what you said now and the way you said it was
+ very different
+ <braunr> maybe, it's 3am, i'm sick and exhausted :)
+ <teythoon> more abstract
+ <braunr> when i give an opinion
+ <braunr> actually, when anyone gives an opinion
+ <braunr> i consider it implicit that it's their point of view alone
+ <braunr> they're not enforcing anything
+ <braunr> merely speaking out
+ <teythoon> people tend to overestimate the importance of their own opinion
+ <braunr> hm i wouldn't say so
+ <braunr> and that's probably why the "who" doesn't matter a lot to me
+ <braunr> it would matter if the person in question had real power
+ <braunr> and his opinion could have a strong influence
+ <braunr> in which case it wouldn't be overestimated
+ <braunr> i could say what i think to systemd people
+ <antrik> teythoon: quite frankly, I'm not sure what you are complaining
+ about. the systemd followers are trying to impose their opinions on
+ various projects. other people (including braunr and me, among many
+ others) are voicing counter-opinions. what's wrong with that?
+ <braunr> but i'm pertty certain the weight they'll associate to what i tell
+ them will be very low :)
+ <braunr> antrik: he called it "annoying whining"
+ <braunr> i think it's the only problem
+ <antrik> braunr: I don't think the systemd people associate much weight to
+ *anything* others say... ;-)
+ <braunr> heh :)
+ <braunr> to make an historic analogy
+ <braunr> it seems to me they're repeating the same mistakes others did
+ during the unix wars
+ <teythoon> antrik: but when you say "the systemd followers are trying to
+ impose their opinion on various projects", don't you dismiss the
+ possibility that the gnome3 people just want to make external displays
+ hot-pluggable?
+ <braunr> of course they do
+ <braunr> don't you dismiss that proprietary software author just want to
+ make money ?
+ <teythoon> no
+ <braunr> well, if that's the only thing you keep in mind to make your
+ opinion, you'll miss important points
+ <teythoon> that is an example of course
+ <braunr> they're sacrificing interchangeability and starting a possibly
+ major rift in the community for hot pluggable displays
+ <braunr> it may not be worth it
+ <teythoon> not supporting stuff like that might make the whole ecosystem
+ obsolete
+ <braunr> i'm not saying it shouldn't be done
+ <braunr> i'm saying it should be done while sacrificing other important
+ things
+ <braunr> it would just take a little mort effort
+ <braunr> and even if it wasn't done
+ <teythoon> that's what i meant by "whining"
+ <teythoon> no offense
+ <braunr> what is the problem of it being "obsolete" ?
+ <teythoon> but talk is cheap, offering alternative solutions is hard
+ <braunr> isn't unix obsolete ? isn't xorg obsolete ?
+ <braunr> hum no
+ <teythoon> no one did, so they implemented their nice features
+ <braunr> the point isn't to offer alternative solutions
+ <braunr> it's to make them possible
+ <braunr> or at least, not deny their technical feasibility because they
+ don't care
+ <braunr> teythoon: see, "interchangeability and starting a possibly major
+ rift" don't look to conflict with your personal goals
+ <braunr> that's the point where i think i can no longer do anything to
+ convince you
+ <braunr> so i'll head to bed :)
+ <teythoon> heh, me too :)
+ <braunr> honestly, i don't care a lot
+ <braunr> i mean
+ <braunr> it won't change much for me
+ <braunr> but again, my brain is wired to think of things as a whole
+ <braunr> on that note, good night :)
+ <teythoon> good night :)
+ <antrik> teythoon: again, IT'S NOT ABOUT DISPLAYS
+ <antrik> believe me, I do have some understanding how display hotplugging
+ works
+ <antrik> also, the problem is not that gnome3 supports logind. the problem
+ is that gnome3 works *only* with logind now AIUI
+ <antrik> there is yet another way to state the fundamental problem
+ <antrik> there is a kind of social contract among free software projects:
+ every maintainer takes a reasonable amount of extra effort to support use
+ cases beyond his own. in return, his use cases are supported by other
+ maintainers
+ <antrik> the systemd guys are breaking this contract, by explicitly
+ refusing, up front, to take *any* effort to accomodate other projects'
+ needs

+ <braunr> heh
+ <teythoon> which reminds me
+ <teythoon> if we want to state our position wrt the default init system
+ debate we should probably do it right now
+ <braunr> yes
+ <teythoon> ml or collaborative editor ?
+ <azeem_> well, tech-ctte chair called the vote only for the default init
+ system for the Linux-ports
+ <azeem_> the vote got shot down on technicalities, but that might stand
+ <azeem_> I think that is a good thing, cause it implies that not one init
+ system has to be adopted across all ports
+ <teythoon> we talked the other day that it might make sense just to state
+ our view and our needs
+ <azeem_> sure.
+ <azeem_> I think what's needed is (i) an init-system agnostic system to set
+ the enable/disable state of services (ii) possibly mandating a .ini-style
+ config file along the style of whatever init system gets chosen as
+ default for Linux, to be used by non-Linux init systems as inut
+ <azeem_> input*
+ <azeem_> just my 0.02 EUR
+ <teythoon> uh
+ <braunr> looks overkill
+ <teythoon> i was thinking more along the lines of 1) we have never used the
+ default debian init system and are cool with not using the default in the
+ future, 2) we intend to use sysvinit in the future, 3) to that end, we
+ ask the init script machinery to be left in place
+ <braunr> but then, people managed to write stuff like libvirt
+ <braunr> so who knows
+ <teythoon> 4) we will help maintaining it as part of our porter effort
+ <braunr> i agree with teythoon
+ <teythoon> 5) we look forward to using openrc as incremental improvement,
+ complementing our sysvinit boot solution
+ <braunr> yes that would be nice
+ <teythoon> i'll write a draft to debian-hurd, ok ?
+ <gnu_srs> openrc now has a dependency loop resolver, so parallel would
+ work:)
+ <teythoon> so is insserv, isn't it ?
+ <gnu_srs> there were complaints on openrc
+ https://bugs.gentoo.org/show_bug.cgi?id=391945 in the tech-ctte
+ discussions, now fixed
+ <azeem_> gnu_srs: please accept the fact that openrc will not be picked by
+ the tech-ctte for the Linux ports
+ <gnu_srs> azeem_: I do, I'm referring to arguments during the discussion
+ (history)
+ <azeem_> sure, just checking
+ <ArneBab> teythoon: your post is being used to portray systemd cgroups
+ treatment as the right way…
+ <teythoon> ArneBab: so ?
+ <braunr> it probably is the right way
+ <braunr> that's not the problem
+ <ArneBab> do you want to clear that up? (do I remember correctly that you
+ did not like that way?)
+ <braunr> we don't like the cgroups interface
+ <teythoon> i will
+ <braunr> not the feature
+ <ArneBab> braunr: that’s what I meant
+ <teythoon> exactly
+ <braunr> the feature amounts to resource containers in the hurd critique
+ ...
+ <braunr> we do want that too :)
+ <braunr> anatoly: you want them to rewrite cgroups ?
+ <braunr> err
+ <braunr> ArneBab: ^
+
+[[dbus_in_linux_kernel]].
+
+ <teythoon> i've been thinking
+ <teythoon> maybe the magic write stuff isn't that bad after all
+ <braunr> :)
+ <braunr> i was thinking the same thing actually
+ <teythoon> i mean, it's not the nicest thing, but it shows how flexible our
+ solution is
+ <braunr> the hurd is a lot about glue code already so why not
+ <teythoon> the problem is that there is no way to test cgroupfs
+ <teythoon> the main user is systemd, and it requires tons of other stuff
+ <braunr> right
+ <teythoon> any other user of cgroups is also probably using other
+ linux-interfaces too

+ <gnu_srs> About openrc having a dependency loop resolver: <teythoon>: so is

+ <gnu_srs> I found is_loop_detected() in insserv/listing.c but that one just

+ * youpi trying the new sysvinit
+ <youpi> hopefully we'll then be able to at last use the proper ifup/ifdown
+ debian way for networking :)
+ <youpi> teythoon: why leaving hurd's runsystem by default rather than
+ sysvinit's?
+ <youpi> ah, another issue, too, now that /dev/vcs appears in /proc/mounts,
+ umountfs would umount it
+ <youpi> ideally umountfs would not umount passive translators
+ <youpi> we could blacklist /dev/vcs in umountfs, but the same issue would
+ happen for user-defined translators in their own home, for instance

+ <gnu_srs> booting with the new sysvinit and openrc versions: works:), but
+ only in recovery mode:-( Hangs before INIT: version 2.88 booting
+ <gnu_srs> after start ext2fs: Hurd server bootstrap: ext2fs[device:hd0s1]
+ exec init proc authtask c1120dc8 deallocating an invalid port 134517370,
+ most probably a bug.
+ <gnu_srs> related or an openrc problem? will test with sysv-rc
+ <youpi> I don't have such issue with sysv-rc
+ <gnu_srs> k!
+ <gnu_srs> shouldn't recovery mode mean starting in runlevel 1, I get
+ runlevel 2?
+ <youpi> it should
+ <pere> gnu_srs: recovery mode normally mean single user, which is between
+ rcS and rc2
+ <gnu_srs> I get INIT: Entering runlevel: 2
+ <pere> rcS.d should really have been named rcboot.d, as that is really what
+ it is.
+ <youpi> ah, right, recovery is not single
+ <youpi> (single as in init 1)
+ <pere> runlevel 1 is not single user either. it is more a gateway into
+ single user. see /etc/init.d/single to see what happen at the end of
+ runlevel 1.
+ <gnu_srs> init 1 and init 2 seems to work
+ <gnu_srs> well, the openrc dependency loop detector has found an init
+ script loop, maybe it has to be fixed?
+ <gnu_srs> disabling the hurd console solved the dependency loop problems,
+ thanks openrc;-)
+ <gnu_srs> (have to dig deeper to see where the loop is, and how to solve
+ it)

+ <gnu_srs> Hi, does the hurd console work with sysv-rc: In operc I get with
+ #console -d vga -d pc_mouse --repeat=mouse -d pc_kbd --repeat=kbd -d
+ generic_speaker -c /dev/vcs
+ <gnu_srs> console: Console library initialization failed: Not a directory
+ <teythoon> gnu_srs: yes, it works with sysvrc
+ <teythoon> gnu_srs: check that /dev/vcs has the appropriate translator
+ record
+ <gnu_srs> showtrans /dev/vcs: empty on another box: /hurd/console
+ <teythoon> yes, fix that and your console will be fine
+ <gnu_srs> settrans /dev/vcs /hurd/console?
+ <gnu_srs> or should it be active?
+ <teythoon> no, set an passive translator record so that this will be
+ persistent
+ <gnu_srs> something is wrong: when starting the hurd console screen is
+ blanked (and hangs)
+ <gnu_srs> can I get the hurd console when running with the serial console
+ (to see boot messages)?
+ <teythoon> gnu_srs: yes, yuo can
+ <gnu_srs> will try that image then, tks:)
+ <gnu_srs> teythoon: how to create all underlying directories? ls /dev/vcs:
+ 1 2 3 4 5 6
+ <teythoon> don't, /hurd/console takes care of that
+ <gnu_srs> is settrans /dev/vcs /hurd/console correct?
+ <teythoon> yes
+ <sjbalaji> What are those underlying directories representing ?
+ <teythoon> the hurd console is a console multiplexer
+ <teythoon> bringing multiple virtual consoles to the hurd
+ <teythoon> # showtrans /dev/tty1
+ <teythoon> /hurd/term /dev/tty1 hurdio /dev/vcs/1/console
+ <gnu_srs> aha: console -d vga -d pc_mouse --repeat=mouse -d pc_kbd
+ --repeat=kbd -d generic_speaker -c /dev/vcs
+ <gnu_srs> task c1120e70 deallocating an invalid port 1782, most probably a
+ bug.
+ <sjbalaji> teythoon: Is it that /dev/tty1 has multiple translators ?
+ <teythoon> no
+ <teythoon> exactly one translator is bound to any given node in the vfs
+ <gnu_srs> something is strange with the hurd console: booting with it
+ enabled still runs the mach console, halting:
+ http://paste.debian.net/79438/
+ <teythoon> what is strange about taht ?
+ <gnu_srs> when starting the hurd console: task c1120e70 deallocating an
+ invalid port 1782, most probably a bug.
+ <teythoon> so ?
+ <gnu_srs> and the paste when halting: twice
+ <teythoon> that is a known issue
+ <gnu_srs> with the hurd console?
+ <teythoon> how do you know it's the hurd console ?
+ <teythoon> that message comes from the kernel
+ <teythoon> currently, it is not possible to tell which process is
+ responsible
+ <teythoon> b/c the task is given as a pointer to the kernel task structure
+ <teythoon> not as a pid
+ <gnu_srs> I don't ,it is triggered by it at least
+ <teythoon> currently there is no way to map the former to the latter
+ <teythoon> why do you think it's a problem ? is something not working as
+ expected ?
+ <gnu_srs> maybe a reproducible way to hunt that bug!
+ <teythoon> we have one already
+ <teythoon> it happens every time the hurd boots
+ <gnu_srs> yes, hurd console does not start, even when enabled:-(
+ <teythoon> then please say so ;)
+ <gnu_srs> I did: (11:23:30) srs: something is strange with the hurd
+ console: booting with it enabled still runs the mach console, halting:
+ http://paste.debian.net/79438/
+ <teythoon> where do you say that the hurd console did not start ?
+ <gnu_srs> maybe it is easier to hunt the bug in an already booted system
+ <teythoon> you just said that the mach console is still active, wich it is
+ even if the hurd console starts
+ <teythoon> yes
+ <teythoon> please start the hurd console by hand
+ <teythoon> -d current_vcs -c /dev/vcs -d vga -d pc_kbd --keymap us
+ --repeat=kbd -d pc_mouse --protocol=ps/2 --repeat=mouse
+ <teythoon> err
+ <teythoon> /bin/console -d current_vcs -c /dev/vcs -d vga -d pc_kbd
+ --keymap us --repeat=kbd -d pc_mouse --protocol=ps/2 --repeat=mouse
+ <gnu_srs> when I log in I have the mach console not the hurd console
+ <teythoon> yes, log in as root, then run that command
+ <gnu_srs> I've done that: (11:10:27) srs: aha: console -d vga -d pc_mouse
+ --repeat=mouse -d pc_kbd --repeat=kbd -d generic_speaker -c /dev/vcs
+ <gnu_srs> please read?
+ <teythoon> and you discovered in that process that /dev/vcs lacked a
+ translator record
+ <teythoon> did you run it again after fixing that ?
+ <gnu_srs> the reply was: (11:10:27) srs: task c1120e70 deallocating an
+ invalid port 1782, most probably a bug.
+ <teythoon> well, if you are feeling that what i ask you to do is
+ unreasonable, i'm not sure how i can help you
+ <gnu_srs> yes, the translator was running!
+ <teythoon> you could hunt down the port deallocation bug, that'd be awesome
+ and most welcomed
+ <teythoon> but i don't believe it is causing your console malfunction
+ <gnu_srs> I did what you asked for??
+ <gnu_srs> I'll do it again!
+ <gnu_srs> ok, now I don't get that error, but still no hurd console? the
+ process is running, logging out and then in, no hurd console.
+ <gnu_srs> not possible in serial console?
+ <teythoon> no, the hurd console is displayed using the graphic card
+ <teythoon> you asked for that with -d vga ;)
+ <teythoon> not sure if there are any other display drivers
+ <teythoon> when you asked whether you can use the serial line, i assumed
+ you used both qemus graphic terminal and a serial console
+ <teythoon> try kvm ... -serial telnet::1236,server,nowait, then use telnet
+ localhost 1236 to connect to the serial console
+ <teythoon> then, you can start the hurd console over the serial console and
+ see whether that worked
+ <gnu_srs> OK; that's what I asked before. I tried with the graphic one,
+ I'll try again
+ <gnu_srs> telnet output is empty
+ <gnu_srs> frozen
+ <teythoon> did you start a getty there ?
+ <gnu_srs> in hurd?
+ <teythoon> b/c if you dropped the console=com0 argument from you gnumach
+ command line, the mach console will be put on the vga screen, not on the
+ serial console
+ <gnu_srs> I dropped console=com0 from grub.cfg, yes
+ <teythoon> ok
+ <teythoon> so simply no one is talking to the serial port anymore
+ <teythoon> did you try to start the hurd console ?
+ <gnu_srs> I did before, can do it again
+ <gnu_srs> startin the HC blanks the screen, and freezes the vga output:-(
+ ssh still working
+ <teythoon> hm
+ <teythoon> try ps Ax | grep tty, are there any term servers running for
+ /dev/tty1..6 ?
+ <gnu_srs> lplenty of them: http://paste.debian.net/79442/
+ <teythoon> good, even gettys are there
+ <gnu_srs> and the console translator runs
+ <teythoon> hm
+ <gnu_srs> root 1224 5 7 months /hurd/console
+ <gnu_srs> root 1227 1226 7 months /bin/console -d vga -d pc_mouse
+ pc_mouse -d pc_kb...
+ <teythoon> yes, everything looks good
+ <teythoon> just to be sure, you are currently using the qemus graphical
+ frontend, right ?
+ <gnu_srs> yes
+ <teythoon> hm :/
+ <teythoon> gnu_srs: do you see loginpr processes ?
+ <gnu_srs> nope
+ <teythoon> hum
+ <teythoon> this strikes me as odd
+ <teythoon> on my system, i see no gettys but only loginpr processes
+ <teythoon> this is b/c the hurd getty does little other than to print some
+ text and run the login program
+ <teythoon> but on your system the getty sticks around
+ <teythoon> is /sbin/getty really the hurd getty? it's easily recognized by
+ its crappieness:
+ <teythoon> /sbin/getty --help || echo $?
+ <teythoon> 1
+ <gnu_srs> 1
+ <teythoon> hm
+ <teythoon> still funny though
+ <teythoon> you could try to run the hurd console, then run a getty manually
+ <teythoon> e.g. /sbin/getty 38400 tty1
+ <gnu_srs> from the ssh login?
+ <teythoon> yes
+ <gnu_srs> then the graphic display is back showing the loin prompt:P
+ <teythoon> weird
+ <teythoon> well, so most things work
+ <teythoon> that's a good thing
+ <teythoon> funny that hurds getty should get stuck like this
+ <gnu_srs> and the terminal is hurd:-)
+ <teythoon> any chance you can produce a stack trace of one of your getty
+ processes ?
+ <gnu_srs> how?
+ <teythoon> gdb --pid=the_pid /sbin/getty
+ <teythoon> then, do bt like usual
+ <gnu_srs> so you mean tty2-6 are broken?
+ <teythoon> no
+ <teythoon> it's just for some reason your gettys do not behave nicely when
+ run from init
+ <gnu_srs> from running tty2: bt #0 0x01087b09 in ?? ()
+ <gnu_srs> #1 0x00000000 in ?? ()
+ <gnu_srs> not much
+ <teythoon> hm :/
+ <teythoon> indeed
+ <teythoon> our getty logs to syslog, can you see anythign of interest here
+ ?
+ <gnu_srs> Jan 31 12:00:46 debian-openrc-20140123 rsyslogd-2066: could not
+ load module '/usr/lib/rsyslog/imklog.so', dlopen:
+ /usr/lib/rsyslog/imklog.so: undefined symbol: klogAfterRun
+ <gnu_srs> [try http://www.rsyslog.com/e/2066 ]
+ <gnu_srs> nothing tty releated
+ <teythoon> gnu_srs: oh, i just noticed, please look into auth.log, the
+ getty stuff ends up there
+ <gnu_srs> teythoon: http://paste.debian.net/79465/
+ <teythoon> well, that is interesting :)
+ <gnu_srs> /dev/tty1 not a directory?
+ <teythoon> for instance, yes
+ <teythoon> it says bad syntax if it was invoked in the wrong way, i.e. not
+ with exactly two arguments
+ <teythoon> that might have been you yourself, right ?
+ <teythoon> with getty --help i mean
+ <teythoon> for the not a directory message, please verify that
+ <teythoon> # showtrans /dev//tty1
+ <teythoon> /hurd/term /dev/tty1 hurdio /dev/vcs/1/console
+ <teythoon> and stat /dev/vcs/1/console says it's a character special file
+ <gnu_srs> I used exactly: /sbin/getty --help || echo $?
+ <teythoon> yes, that accounts for that bad syntax message
+ <gnu_srs> what so bad about that?
+ <gnu_srs> showtrans /dev//tty1
+ <gnu_srs> /hurd/term /dev/tty1 hurdio /dev/vcs/1/console
+ <teythoon> getty is so simple minded that it doesn't really parse its
+ arguments
+ <gnu_srs> stat: http://paste.debian.net/79469/
+ <teythoon> looks nice
+ <teythoon> everything looks nice, i'm at my wits end here
+ <gnu_srs> and everything works OK with sysv-rc?
+ <teythoon> yes
+ <teythoon> by the way, are you using the sysvinit init scripts or something
+ openrc related ?
+ <gnu_srs> openrc use all the scripts in /etc/init.d
+ <teythoon> actually, could you try to kill -HUP 1 ?
+ <gnu_srs> BTW: the dependency loop detector has found many loops in those
+ scripts
+ <gnu_srs> kill -HUP 1: nothing happens
+ <teythoon> ok, try to kill one of those gettys and see if the one that
+ respawns works
+ <teythoon> then again, the getty should try to reopen the device every
+ minute until it succeeds
+ <gnu_srs> getty tty1 and tty2 disappeared? kill -HUP tty3 respawns
+ immediately
+ <gnu_srs> now no getty processes are left?
+ <gnu_srs> /dev//tty4: Not a directory etc?
+ <teythoon> sorry, i should have expressed myself more clearly
+ <teythoon> kill -HUP 1 sends a SIGHUP to sysvinit, this makes it reload
+ it's configuration
+ <teythoon> when i said kill some getty, i meant just kill some_pid
+ <teythoon> when you said 'kill -HUP tty3 respawns immediately', did you
+ mean you killed the getty that was listening on /dev/tty3, and then a new
+ one appeared and you got a login prompt at tty3 ?
+ <gnu_srs> a new pid appeared, the login prompt is on tty1
+ <gnu_srs> this one? /hurd/term /dev/tty1 hurdio /dev/vcs/1/console
+ <teythoon> i'd like to invite you to look at daemons/getty.c
+ <gnu_srs> not a big piece of code: anything specific?
+ <teythoon> no, just look what it roughly does
+ <gnu_srs> not a directory is not coming from that code
+ <teythoon> correct
+ <gnu_srs> it execl-s login
+ <teythoon> yes
+ <teythoon> inevitably
+ <teythoon> but you do not observe this
+ <gnu_srs> how come when they are running?
+ <teythoon> this is the question that you will have to answer in order to
+ make any progress
+ <gnu_srs> I killed only one of them: kill -HUP 1031 and they all
+ disappeared
+ <teythoon> i thought along these lines: the most obvious way to stall getty
+ is if it never exits that loop
+ <teythoon> so i guessed it might be failing to open the device
+ <teythoon> we already observed that getty works fine if invoked by you
+ manually
+ <teythoon> the question thus is, what is different when getty is invoked by
+ init ?
+ <teythoon> if a process started by init in this way is killed, init will
+ restart it
+ <teythoon> please note, that if anyone says kill that process, she means
+ send a signal that results in process termination
+ <teythoon> and while sighup causes processes to die if the signal is not
+ handled, it is not the ideal signal to kill processes
+ <teythoon> b/c some processes handle sighup
+ <teythoon> like sysvinit, which reloads its configuration
+ <teythoon> many daemons do this
+ <teythoon> see 'man 7 signal' for how signals affect processes
+ <gnu_srs> sorry, have to leave for now, bbl and thanks a LOT so far:)
+ <teythoon> ok :)
+ <teythoon> you are welcome :)
+ <gnu_srs> teythoon: I'm back but cannot spend to much time on this
+ tonight. Maybe you should try it yourself, do you want another image on
+ my box?
+ <teythoon> it'd be nice if you put your packages somewhere
+ <gnu_srs> there are no special packages sysvinit (-46) and openrc (-8)
+ <teythoon> surely openrc with some patches ?
+ <gnu_srs> from #openrc: (17:37:41) srs: start with sysvinit and make it
+ work first!
+ <gnu_srs> (17:28:43) srs: zigo: Then I copied that working image to
+ another, and changing hostname, and continued from there.
+ <gnu_srs> openrc with the hurd patches for /lib/rc/sh/init.sh (v8 should be
+ available from experimental by now)
+ <teythoon> sweet :)
+ <teythoon> gnu_srs: maybe it was just some weird issue with your system
+ <teythoon> i just switched to openrc and everything seems to just work
+ <teythoon> i'll redo what i just did more cleanly to get a clean test vm...
+ <gnu_srs> nice:)
+ <gnu_srs> teythoon: And you got the hurd console?
+ <teythoon> heh, i believe so >,<
+ <teythoon> i didn't see it b/c i was using --nographic
+ <teythoon> but ps Ax looked alright
+ <teythoon> hrm
+ <teythoon> gnu_srs: i can reproduce your trouble, umount still strips the
+ translator record from /dev/vcs
+ <teythoon> at system shutdown time
+ <gnu_srs> so that's the reason. Additionally I have to issue halt twice
+ from a ssh login, see http://paste.debian.net/79517/
+ <teythoon> funny indeed
+ <teythoon> gnu_srs: i can reliably recover the hurd console by doing
+ <teythoon> settrans /dev/vcs /hurd/console && service hurd-console restart
+ && pkill getty ; sleep 5 ; pkill getty
+ <teythoon> humm, as you say, halt doesn't work

+ <pere> I was able to boot in recovery mode. :)
+ <pere> and this time sysvinit booted. saw a segfault message just after

+ <pere> looks like it is startpar that segfaults.
+ <pere> looks like the invalid port message come every time, no matter if

+ <pere> I was wrong. it isn't startpar segfaulting, it is something in
+ rcS.d/.
+ <pere> bootlogd is the process segfaulting at boot.
+ <pere> looks like the boot success rate is 30% or so.
+ <pere> reported bootlogd problem as <URL: http://bugs.debian.org/737375 >.
+ I really miss valgrind. :)
+ <teythoon> pere: yes, the invalid port message is from the exec server
+ <teythoon> pere: i see the hurd boot process hang sometimes, no matter if i
+ use sysvinit or not
+ <teythoon> i believe it's a race condition in the ext2fs, not sure though
+ <pere> teythoon: but did the frequency of the hang go up with sysvinit or
+ not? to me it seem like that.
+ <teythoon> pere: yes, i believe it got worse
+ <teythoon> what hangs is fsysopts --update /
+ <teythoon> runsystem.sysv does that quite early
+ <pere> able to debug it?
+ <pere> I like the fact that runsystem.sysv set up ip at boot time, while

+ <pere> it is quite confusing that hurd got two init processes with

+ <zigo> Or maybe go in recovery mode?
+ <teythoon> depends
+ <teythoon> do you use sysvinit ?
+ <teythoon> do you use the hurd packages from hurd-ci ?
+
+
+## IRC, OFTC, #debian-hurd, 2014-02-05
+
+ <zigo> teythoon: Sorry, didn't see your reply. I just used the Hurd image,
+ untar it, and apt-get update / dist-upgrade. That's it, nothing more or
+ less.
+ <zigo> teythoon: I obviously would like to install sysvinit, and later
+ OpenRC. That's the reason why I'm running Hurd: to make sure OpenRC works
+ with it without issues.
+ <zigo> teythoon: It seems it "sometimes work" or what???
+ <zigo> I was able to repair it using the recovery mode, it seems.
+ <zigo> grrr...
+ <zigo> I got this issue again, again and again ...
+ <zigo> Sometimes, got the tty1, sometimes, it doesn't appear.
+ <zigo> That's REALLY frustrating.
+ <pere> zigo: and yes, the success rate for boot is not 100%. it increases
+ a bit by using the packages teythoon created at hurd-ci.
+ <pere> apparently some race condition somewhere.
+ <zigo> pere: So, I should just try and reboot again and again ?
+ <zigo> pere: Is it improving after switching to sysvinit?
+ <pere> once I had to boot six times before I got it running...
+ <pere> I was told that the race involves a call to fsysopts, and that the
+ success rate with sysvinit was smaller because fsysopts command was
+ called earlier. I can not confirm nor deny this.
+ <pere> with the latest packages from hurd-ci the success rate is almost
+ 100% again.
+ <zigo> pere: Where do get that?
+ <pere> zigo: see <URL:
+ http://people.skolelinux.org/pere/blog/Testing_sysvinit_from_experimental_in_Debian_Hurd.html
+ >
+ <zigo> pere: What's the "update-alternatives --config runsystem" for?
+ <pere> to switch to sysvinit
+ <zigo> Right, that's what I was missing then! :)
+ <pere> the new sysvinit version in unstable was built for hurd one and a
+ half hour ago. so soon hurd users can skip experimental for that.
+ <zigo> pere: I've just succeeded in booting with OpenRC! :)
+ <zigo> Though this console pb is REAAAALLLYYYY getting on my nerves! :)
+ <zigo> Also, any idea why we don't get the nice colorfull output when
+ booting?
+ <zigo> When booting with OpenRC, I've noticed that the dependency loop
+ detects some loops with the hurd-console thing.
+ <teythoon> zigo: good to hear that you got it working
+ <teythoon> the console problem is the following
+ <teythoon> when you shutdown using sysvinit, the system will run umount -a
+ <teythoon> it will then mistake some translators (like the one on /dev/vcs)
+ for file systems and remove their passive translator records
+ <teythoon> you can fix this by running '/usr/lib/hurd/setup-translators -k
+ -p'
+ <teythoon> you can avoid it for the time being by using reboot-hurd or
+ halt-hurd
+ <pere> teythoon: btw, how often is the hurd boot image available for
+ download updated?
+ <teythoon> not very often
+ <zigo> teythoon: Can I run '/usr/lib/hurd/setup-translators -k -p'
+ mounting my hurd image in a chroot?
+ <zigo> Hum...
+ <zigo> Probably better to do that in the recovery mode, no? :)
+ <youpi> dpkg-reconfigure hurd
+ <youpi> would be easier to type :)
+ <youpi> but we really need to fix that /dev/vcs unmounting
+ <pere> missing working getty and missing symlink from /run/mtab to
+ /proc/mount are the most serious problems I still see.
+ <zigo> The recovery mode doesn't work with OpenRC ! :(
+ <zigo> (it does in kFreeBSD and Linux, not with hurd ...)
+ <zigo> What happens is that it continues to runlevel 2.
+ <zigo> How can I fix then?
+ <youpi> pere: missing working getty?
+ <youpi> I don't see what issue you are referring to
+ <youpi> about the missing symlink, I'm wondering what is supposed to add it
+ <youpi> zigo: I don't know if anybody investigated it yet
+ <pere> youpi: yes, after boot there is no login prompt.
+ * pere have no idea, suspect a script in initscripts.
+ <zigo> youpi: I'm reffering to the fact that I have no login prompt after
+ boot, and that I don't know how to fix, since I don't have a recovery
+ mode to my disposal anymore.
+ <youpi> pere: but is the console started?
+ <youpi> (I mean the hurd console)
+ <zigo> pere: I suspect a wrong dependency, which OpenRC by the way, prints.
+ <youpi> pere: otherwise, unless you have a /dev/console getty in
+ /etc/inittab, it's expected you don't have a prompt
+ <youpi> zigo: add
+ <youpi> c:23:respawn:/sbin/getty 38400 console
+ <youpi> to your /etc/inittab
+ <teythoon> youpi: yes, we need to get that fixed
+ <youpi> grrrr
+ * youpi wanted to change the image file on people.d.o
+ <youpi> but I can't do that without downloading it on my laptop, to be able
+ to modify it
+ <youpi> I would have been, if people was a hurd system :)
+ <teythoon> the proper way to fix this is to implement the get_source stuff
+ and get rid of the heuristic in mtab.c
+ <pere> youpi: nope, no console process running.
+ <youpi> then that's why, /dev/vcs got unmounted
+ <pere> I already have a console getty in inittab. got it from the last
+ sysvinit package
+ * youpi should have brown-bag-fixed these bugs before this week-end

+ <youpi> pere: but you don't get a getty prompt on the mach console? I don't
+ understand why
+ <youpi> it does work for me
+ <teythoon> brown-bag-fixed ?
+ <zigo> youpi: Adding that in /etc/inittab didn't fix anything.
+ <youpi> yes, ugly hacks uploaded to debian-ports
+ <youpi> zigo: even with rebooting?
+ <youpi> could you snapshot your screen so we can make sure what you are
+ actually getting?
+ <zigo> youpi: I did it mounting my partition in a loopback...
+ <zigo> Then booted up, and still couldn't see the console prompt.
+ <youpi> ok, but please take a snapshot, so we are sure what is actually
+ happening
+ <youpi> whether the console starts, etc.
+ <pere> that info passed out of the screen and is not shown after my boot,
+ at least.
+ <youpi> which info?
+ <youpi> again, please take a snapshot of the screen
+ <youpi> otherwise we are just guessing, and that's never good for debugging
+ <zigo> Maybe you'll find this interesting: http://paste.debian.net/80246/
+ <zigo> This is the output of OpenRC booting and detecting dependency loops
+ in the LSB header scripts.
+ <pere> youpi: the info about the console being started or not. I'll show
+ you, give me a minute.
+ <youpi> zigo: well, that shouldn't be more problems than the dependency
+ loop already existing between rc.local and rmnologin
+ <pere> youpi: any loop is a fatal problem.
+ <youpi> how come the rc.local vs rmnologin is not a problem ?
+ <zigo> With sysv-rc in Debian, there's all sorts of loops that are just
+ silent.
+ <pere> I have not seen that loop on my linux system, so I am unsure what
+ you talk about.
+ <youpi> (the actual issues is simply that all three use Required-start:
+ $all, and thus all depend on each other)
+ <zigo> That's a huge pb IMO.
+ <youpi> pere: well,
+ <pere> zigo: show me one?
+ <youpi> rc.local:# Required-Start: $all
+ <youpi> rmnologin:# Required-Start: $remote_fs $all
+ <zigo> Yeah, the $all is just *bad*.
+ <pere> that is no loop.
+ <zigo> I do believe we should implement a lintian warning about it.
+ <pere> sure, $all do not behave the way most people expect, and should be
+ avoided as much as possible.
+ <pere> any other loops?
+ <youpi> no
+ <youpi> (not that I know of)
+ <pere> youpi: sending you the screenshot via irc.
+ <youpi> uh, long time no use dcc send, I don't even know where it sent it
+ to :o)
+ <pere> ok. aborting and trying another approach.
+ <pere> http://www.picpaste.com/booted-herd.png
+ <youpi> ok, so boot didn't actually finish
+ <youpi> that's why you don't get gettys or hurd-console (which is last)
+ <youpi> there must be some init script hanging in the meanwhile
+ <pere> logging in via ssh show no running startpar process, so I doubt that
+ is the case.
+ <pere> syslog contain this: Feb 5 10:10:27 hurdtest console[808]: Console
+ library initialization failed: Not a directory
+ <youpi> that is due to /dev/vcs not mounted
+ <youpi> but that should have not prevented the boot from completing...
+ <pere> the boot is completed, as far as I can tell.
+ <youpi> you can disable the hurd console in /etc/defaults/hurd-console
+ <youpi> do you have gettys running?
+ <pere> no such file.
+ <youpi> oops, -s
+ <pere> http://paste.debian.net/80251/
+ <teythoon> pere: check your /etc/inittab, is there a getty for the mach
+ console ?
+ <youpi> he said yes earlier
+ <teythoon> oh ok
+ <teythoon> i wonder why it doesn't show up then
+ <youpi> same for me
+ <teythoon> if the getty cannot open the device, it will loop
+ <pere> ah, I was wrong. the inittab is not the one I thought. the current
+ one is after a reinstall, while I checked the content before that.
+ <teythoon> pere: check /var/log/auth.log
+ <pere> there is indeed no console entry in /etc/inittab. I thought it
+ would be copied into place during upgrades?
+ <teythoon> not if it exists
+ <teythoon> iirc
+ <youpi> indeed
+ <pere> ah, great. "cp /usr/share/sysvinit/inittab /etc/inittab" and a
+ reboot fixed it. :)
+ <youpi> phew :)
+ <pere> it really should try harder to update the inittab on hurd to a
+ working one.
+ <teythoon> didn't i do something like this to fix the getty path ?
+ <pere> yes. that was the code I expected to solve this.
+ <teythoon> it didn't work ?
+ <pere> well, I had the wrong inittab file...
+ <pere> btw, do hurd have the needed syscalls for bootlogd to work?
+ <teythoon> i haven't looked at bootlogd yet
+ <pere> would be nice to have a text dump of the boot when trying to figure
+ out what went wrong.
+ <teythoon> yes, that'd be nice
+
+ <youpi> pere: could you blacklist /dev/vcs in umountfs, just like already
+ done for /proc|/dev|/.dev etc. ?
+ <youpi> so at least that case, which is really problematic, gets fixed now,
+ and not have to wait for another, more hurdish solution
+ <pere> youpi: just send patches to bts, and I'll pick it up from there.
+ <teythoon> nice. i'll work on the proper solution. bbl

+ <pere> rleigh: yeah, good to see you again. I got a burst of energy and

+ <heroxbd> teythoon: serial console always works, right? no matter how

+ <teythoon> heroxbd: yes
+ <teythoon> but you need a getty on it
+ <youpi> well, just like on linux :)
+ <teythoon> yes
+ <teythoon> almost
+ <teythoon> on mach, we have the mach console. by default that is put on the
+ vga screen, but you can make mach put it on a serial port using the
+ gnumach command line flag console=comX
+ <youpi> well, just like on linux :)

+
+ <gg0> on halt/reboot it can't remount readonly root because it's busy, what
+ makes it busy?
+ <gg0> by keeping /lib/rc/init.d mounted (like /dev/vcs) it shuts down
+ properly
+ <youpi> I don't know about such directory
+ <gg0> so seems that failed readonly remount is not a real problem because
+ at the end it runs halt-hurd/reboot-hurd which umount root properly
+ <youpi> yes
+ <gg0> afaiu it's a tmpfs where openrc copies "itself", kind of work
+ directory
+ <gg0> by removing it, it can't continue working
+ <gg0> at boot some messages are about its creation/population
+ <pere> why do init.d/hurd-console depend on $all? In most cases, depending
+ on $all is not giving you want you expect.
+ <youpi> because we prefer to start the console (and thus clear all the
+ screen) only after the boot has finished
+ <youpi> otherwise the console output will be messed up by the end of the
+ boot messages
+ <teythoon> youpi: there has to be a better way
+ <teythoon> b/c the way it is now, if one spawns a getty on the mach
+ console, it will mess up the hurd console as well
+ <youpi> well, we do want mach messages printed even with the hurd console,
+ at least
+ <teythoon> i once thought that instead of printing them the kernel could
+ send messages to a registered userspace daemon that could e.g. send them
+ to syslog
+ <youpi> that requires syslog to be working at all
+ <pere> changing $all to $local_fs seem to work fine here.
+ <youpi> when the kernel cries out, we'd better always be able to hear it :)
+ <youpi> pere: but then you have the bootup messages in the middle of the
+ console, don't you?
+ <pere> not as far as I can tell. look just the same as before.
+ <youpi> well, on my box it seems that it gets to start after other daemons,
+ by luck
+ <youpi> ah, perhaps getty actually clears the tty?
+ <youpi> then that would be ok
+ <teythoon> youpi: i don't think it does
+ <youpi> well, somehow something clears the output at least
+ <teythoon> i thought he hurd console does this
+ <youpi> it does on startup, yes
+ <youpi> but if it starts before other daemons
+ <youpi> the damons startup output gets over it
+ <youpi> one sees the console clear the screen, then get daemon startup
+ messages, and then the screen gets cleared again before the login prompt
+ appears
+ <teythoon> interesting, i haven't seen this happening
+ <youpi> it seems like it happens when emitting text on /dev/tty1, the
+ console will then clear the screen to make the way for the new output
+ <youpi> and since that happens on getty startup, it happens to be after all
+ daemon startup
+ <youpi> yes, that's what happens
+ <youpi> so considering this, I'm fine with starting the console earlier
+ <youpi> getting a display glitch seems to have been acceptable on Linux for
+ years :)
+ <youpi> (during boot, I mean)
+ <teythoon> ok
+
+ <gg0> anyone else tried openrc?
+ <gg0> 15:20 < pere> yes, it did not umount properly.

+ <gg0> 15:39 < gg0> any typo adding such path?
+ * gg0 likes cross-channel pasting
+ <gg0> anyone else keeps getting unclean umounts even after applying
+ http://paste.debian.net/plain/80386/ ?
+ <teythoon> gg0: yes, me. worked fine, it didn't shut down properly though
+ <gg0> here works like a charm
+ <gg0> what do you mean by properly?
+ <gg0> i see first it can't remount root readonly but at least by not umount
+ path in question it continues executing scripts till actually shut it
+ down with something like {halt,reboot}-hurd
+ <gg0> *not umounting
+ <gg0> *shutting
+ <teythoon> for me it did not shut down
+ <gg0> you mean don't you get classic press ctrl+alt+canc to reboot message?
+ <teythoon> yes
+ <teythoon> from my perspective (and from /hurd/init's), that's not shutting
+ down
+ <teythoon> as in it did not call reboot(2)
+ <gg0> what are configuration not to miss besides switching runsystem to
+ sysv one?
+ <gg0> *configuration steps
+ <teythoon> no idea, i did nothing else but to switch to runsystem.sysv and
+ to install openrc thus replacing sysv-rc
+ <gg0> can you paste shutdown messages somewhere?
+ <teythoon> sure
+ <gg0> .o(world is failing, /me can't debug teythoon :))
+ <teythoon> http://paste.debian.net/hidden/745071e6/
+ <gg0> in my case i just found out that /etc/init.d/umountfs tries to umount
+ /lib/rc/init.d where openrc scripts are
+ <gg0> what if you set VERBOSE and print REG_MTPTS? something like
+ http://paste.debian.net/plain/80570/
+ <gg0> there i got "settrans -apfg /lib/rc/init.d" which vanished with first
+ patch
+ <teythoon> http://paste.debian.net/80573/
+ <gg0> ok and if you apply first patch http://paste.debian.net/plain/80386/
+ <gg0> i.e. adding |/lib/rc/init.d to mount point to ignore
+ <teythoon> didn't help
+ <gg0> well output should change though
+ <teythoon> it does
+ <teythoon> but it still does not shut down
+ <gg0> paste please then
+ <teythoon> http://paste.debian.net/80576/
+ <teythoon> what did you expect ?
+ <gg0> did you unapply VERBOSE & print REG_MTPTS?
+ <teythoon> yes
+ <teythoon> no
+ <teythoon> well
+ <gg0> seems you do, if VERBOSE is set, it prints Will now unmount local
+ filesystems"
+ <teythoon> i restored a vm snapshot, and applied both patches
+ <gg0> instead of "Unmounting local filesystems"
+ <gg0> *seems you did
+ <teythoon> http://paste.debian.net/80577/
+ <teythoon> shall i do it again ?
+ <gg0> and what after "root@debian:/# halt" ? :p
+ <teythoon> 23:55 < teythoon> http://paste.debian.net/80576/
+ <teythoon> and openrc shouting lots of stuff about breaking dependencies
+ <gg0> please yes do it again
+ <gg0> if VERBOSE is set, it prints "Will now unmount local filesystems"
+ instead of "Unmounting local filesystems"
+ <teythoon> yes, you are right
+ <teythoon> still, it does not work
+ <teythoon> http://paste.debian.net/80579/
+ <gg0> i'm curious about the new REG_MTPTS, supposing /lib/rc/init.d has
+ been suppressed
+ <gg0> ok stop
+ <gg0> 23:47 < gg0> ok and if you apply first patch
+ http://paste.debian.net/plain/80386/
+ <teythoon> i did
+ <teythoon> well, i added that path
+ <gg0> i don't believe so, it should ignore it if added
+ <teythoon> did it fix the issue for you ?
+ <gg0> yes
+ <gg0> any typo in addition?
+ <gg0> obviously patch is against sysvinit source but you have to apply it
+ to /etc/init.d/umountfs
+ <teythoon> obviously
+ <gg0> isn't it time to tell me you are kidding me yet?
+ <youpi> pere: thanks for the upload. I happened to realized that since it
+ was in collab-maint, I could as well just commit changes, I hope it's ok?
+ <teythoon> gg0: root@debian:~# fgrep '/lib/rc/init.d' /etc/init.d/umountfs
+ /|/proc|/dev|/.dev|/dev/pts|/dev/shm|/dev/.static/dev|/proc/*|/sys|/sys/*|/run|/run/*|/lib/rc/init.d)
+ <gg0> /dev/vcs is missing, not the latest sysvinit version
+ <gg0> could this affect shutdown?
+ <teythoon> i know
+ <teythoon> possibly
+ <gg0> what if you also add /dev/vcs to path list?
+ <teythoon> what then ?
+ <teythoon> i don't mind /dev/vcs being
+ <teythoon> err, 'umounted'
+ <teythoon> i can handle that just fine
+ <gg0> i mean what happens if you add /dev/vcs to path list in
+ /etc/init.d/umountfs as you did with /lib/rc/init.d?
+ <gg0> what happens = how it shutdown
+ <teythoon> why would it be any different ?
+ <gg0> no idea, seems the only change you don't have
+ <gg0> i just know it fixes hurd console
+ <teythoon> i know it fixes the hurd console b/c i was the one who broke the
+ hurd console in the first place ...
+ <gg0> quite sure there's something wrong on your side
+ <gg0> if it's actually among those path to ignore, it can't be added to
+ REG_MTPTS
+ <gg0> my /proc/mounts http://paste.debian.net/plain/80583

+
+ <gg0> teythoon: sorry for pasting reversed patches
+ <gg0> please apply http://paste.debian.net/plain/80587, halt and paste
+ output + /proc/mounts
+ <pere> youpi: just fine. but please join us on #pkg-sysvinit and make sure
+ to follow the mailing lists.
+ <teythoon> gg0: no, sorry, i was perfectly able to use -R on your patches,
+ as demonstrated by the paste i send
+ <teythoon> i think i'll rather just wait for the next sysvinit package and
+ try it again
+ <gg0> teythoon: i don't doubt you are able, i'm sorry because i messed up
+ things
+ <gg0> /lib/rc/init.d should not go in $REG_MTPTS
+ <gg0> sysvinit 2.88dsf-48 just add /dev/vcs to not-to-umount paths and make
+ boot consider -s for single user, nothing about umounting filesystems on
+ halt/reboot
+ <pere> the /lib/rc/init.d/ change to umountfs seem to be the wrong one, as
+ it do not solve the problem for me. because of this, I have not applied
+ it to git.
+ <gg0> pere: could you try to apply http://paste.debian.net/plain/80587,
+ halt and paste output?
+ <gg0> well it applies to teythoon who doesn't have /dev/vcs
+ <gg0> */dev/vcs change
+ <gg0> pere: this one applies to -48
+ installed. http://paste.debian.net/plain/80615/
+ <gg0> given /lib/rc/init.d is added to not-to-umount paths it can't go in
+ REG_MTPTS
+ <pere> http://picpaste.com/halt-hurd-DVEVoHnr.png
+ <gg0> pere: you didn't apply it
+ <gg0> no messages from umountfs
+ <gg0> which is even more weird
+ <pere> well, patch claimed it did.
+ <gg0> normally it says "Unmounting local filesystems..."
+ <pere> checked the file, patch is applied.
+ <gg0> ok i think i got it
+ <gg0> patch is good. it just requires booting twice _and_ removing
+ non-patched /etc/init.d/umountfs.* if any
+ <gg0> patch = adding /lib/rc/init.d
+ <gg0> so
+ <pere> which files do you need to remove?
+ <gg0> /etc/init.d/umountfs.* and /lib/rc/init.d/started/umountfs.*
+ <gg0> do you have any?
+ <gg0> you should just have patched umountfs under both /etc/init.d/ and
+ /lib/rc/init.d/started/
+ <gg0> the latter is populate at boot, that's why i said twice to become
+ effective
+ <gg0> *populated
+ <gg0> but propably /lib/rc/init.d/started/umountfs can be fixed on the fly
+ <gg0> from start:
+ <pere> why do you need to remove these files?
+ <gg0> 1/ patch /etc/init.d/umountfs by adding /lib/rc/init.d to
+ not-to-umount path list
+ <pere> why are these files not ignored?
+ <gg0> 2/ remove /etc/init.d/umountfs.* if any (eg. .orig .new .whatever)
+ <gg0> pere: because it loads them at boot, you need it loads just the right
+ one
+ <gg0> 3/ reboot twice
+ <gg0> (3/ halt twice)
+ <pere> this sound very fishy to me.
+ <gg0> or 3/ fix umountfs files under /lib/rc/init.d/started as well
+ <gg0> that should make it shutdown properly right away
+ <pere> my halt still hang.
+ <gg0> pere: you have /lib/rc/init.d in both /etc/init/umountfs and
+ /lib/rc/init.d/started/umountfs and there are no umountfs.* around?
+ <gg0> problem seems to be it picks first it finds if there are more than
+ one
+ <gg0> well i could have been more precise: /lib/rc/init.d/started/umountfs
+ is a link to /etc/init.d one
+ <gg0> btw there must be just one and only one umountfs, patched
+ <gg0> pere: clean /etc/init.d, reboot/halt with reboot-hurd or halt-hurd,
+ then next sysv reboot/halt will be good
+ <gg0> you just need to leave patched umountfs under /etc/init.d alone
+ <gg0> patch has always been good, it just needs 2 reboots to be appreciated
+ <gg0> pere: do you have other /etc/init/umountfs* files besides patched
+ one?
+ <gg0> my guess is it takes the first and only the first which Provides:
+ umountfs
+ <gg0> 12:17 < pere> why are these files not ignored?
+ <gg0> 12:35 < gg0> my guess is it takes the first and only the first which
+ Provides: umountfs
+ <gg0> to confirm that, if you have umountfs and umountfs.orig, under
+ /started you'll find just umountfs.orig
+ <gg0> pere: how goes?
+ <gg0> teythoon: last ~40 lines
+ <gg0> i'm assuming you have any else umountfs.* under /etc/init.d. if you
+ just add /lib/rc/init.d path to the only umountfs there should not be any
+ problem
+ <pere> gg0: removing the umountfs.* files did not help, as far as I can
+ tell.
+ <pere> are you telling me that openrc caches all init.d scripts in
+ /lib/rc/init.d/ at boot?
+ <gg0> pere: yes, you can see them. which umountfs* do you have under
+ /lib/rc/init.d ?
+ <pere> the right one. :)
+ <gg0> only the right one?
+ <pere> just scared me to know that changes on the disk do not take effect
+ immediately with openrc.
+ <gg0> pere: only the right one?
+ <pere> yes
+ <gg0> here i screwed it up by forcing initscripts removal and reinstall to
+ reproduce it, then fixed it once again
+ <gg0> i should just improving the explaination :)
+ <gg0> pere: "removing the umountfs.* files did not help," so did you find
+ any?
+ <pere> yes, both .orig, .rej and .dpkg-old
+ <gg0> pere: ok you should find one of them linked under
+ /lib/rc/init.d/started then
+ <gg0> /lib/rc/init.d/started/umountfs.*
+ <pere> I removed them three boots ago. still halt hangs.
+ <gg0> pere: and current umountfs have /lib/rc/init.d in path list?
+ <gg0> *has
+ <pere> yes.
+ <gg0> pere: can you access via ssh to it before issuing halt?
+ <pere> that is how I access it normally.
+ <gg0> ok
+ <gg0> before halt df should list /lib/rc/init.d as well
+ <gg0> after halt it should not, do you confirm that?
+ <gg0> (ssh connection here is kept alive)
+ <pere> my ssh connection went down, but /lib/rc/init.d was mounted while it
+ was active.
+ <pere> to me it look like umountfs isn't executed at all during shutdown.
+ <pere> oh, well. got to work on other things now. :)
+ <gg0> it's correct getting no messages if there no filesystem to umount
+ <gg0> as it wouldn't be run at all
+ <zigo> pere: Hey, thanks for uploading sysv-rc -48 ! :)
+ <pere> you are welcome. :)
+ <gg0> i can't reproduce it on a VM :/ http://paste.debian.net/plain/80658/
+ <gg0> ehm no, same machive, successive halt

+
+
+### IRC, freenode, #hurd, 2014-02-09
+
+ <gnu_srs> (16:31:17) <youpi>: gnu_srs: the -49 version of sysvinit contains
+ a fix for bootlogd
+ <gnu_srs> Nice for kFreeBSD, for Hurd it doesn't matter if we get a
+ segfault or an error code saying it's not implemented :-(
+ <youpi> segfault vs error code is really not the same
+ <youpi> iirc bootlogd would ignore the error
+ <gnu_srs> Nevertheless, bootlogd is not usable on Hurd :(
+ <youpi> then fix it
+
+
+## IRC, OFTC, #debian-hurd, 2014-02-08
+
+ <rleigh> gg0: If the sames are set by hurd itself, then it makes sense to
+ adapt sysvinit to cope with that rather than altering hurd since that
+ would be a fairly major compatibility break. OTOH, adding support for the
+ Linux/FreeBSD names in addition to the hyphenated names would be good
+ from the point of view of better interoperability generally, not just for
+ sysvinit.
+ <rleigh> For now, getting sysvinit to support the Hurd names is easy
+ enough, and if you do add the Linux/FreeBSD names then the compatibility
+ stuff can be removed when that's available.

+
+ <gnu_srs> Hi, still problems with hurd console under openrc: console:
+ Console library initialization failed: Not a directory
+ <gnu_srs> and /dev/vcs is there
+ <youpi> gnu_srs: but is it a directory?
+ <gnu_srs> the output of console -d vga -d pc_mouse --repeat=mouse -d pc_kbd
+ --repeat=kbd -d generic_speaker -c /dev/vcs gives the response above
+ <gnu_srs> looks like /dev/vcs is a file. How to recreate the directory
+ content?
+ <gnu_srs> I thought it should not be removed with the latest sysvinit
+ package (-49)
+ <gnu_srs> from -48 changelog: Tell init.d/umountfs to not umount /dev/vcs,
+ as it break the console on Hurd. Patch from Samuel Thibault.
+ <youpi> gnu_srs: but did your reconfigure the hurd package to remount it ?
+ <gnu_srs> ?
+ <youpi> /dev/vcs won't magically be remounted by just not being unmounted
+ by sysvinit
+ <gnu_srs> dpkg-reconfigure hurd?
+ <youpi> sure
+ <gnu_srs> I can start the console manually, but ENABLE='true' in
+ /etc/default/hurd-console does not work (at least with openrc)
+ <youpi> does /dev/vcs becomes a mere file again with openrc?
+ <gnu_srs> no it's a directory with 6 entries
+ <youpi> does the /etc/init.d/hurd-console gets to starT?
+ <youpi> I'm afraid I'm really asking obvious questions that you should have
+ already asked for yourself
+ <gg0> so you mounted it and it's not a file anymore. does it work now?
+ <gnu_srs> it seem like the service is not started, trying to figure out
+ why:-D
+ <gnu_srs> I can restart it but it is not visible in rc-status?
+
+ <gg0> shutdown stuck at "Asking all remaining processes to
+ terminate...done." (even before distupgrade btw)
+ <gg0> seems stuck at killall5 -18
+ <teythoon> hm, that's bad
+ <teythoon> how do you know that ?
+ <gg0> /etc/init.d/sendsigs and /etc/init.d/killprocs
+ <gg0> (yes, switched to sysvinit and testing openrc)
+ <teythoon> but killall5 -18 is SIGSTOP right?
+ <teythoon> and if it says ...done. then killall5 has already been run
+ <teythoon> so, how do you know it hangs at killall5 ?
+ <gg0> teythoon: "done" is "log_action_end_msg 0" just after killall5 -15,
+ then we should get "Killing all remaining processes" or "All processes
+ ended within $seq seconds."
+ <gg0> Asking all remaining processes to terminate...killall5 -15 -o 956 #
+ SIGTERM...done.
+ <gg0> All processes ended within 1 seconds...done.
+ <gg0> shutdown properly this time
+ <teythoon> hm
+ <teythoon> fwiw, i've also encountered hangs, haven't investigated yet
+ <gg0> with openrc?
+ <teythoon> yes
+
+ <gnu_srs> Is it so that with teythoons mtab translator umount -a unmounts
+ all passive translators, removing the translator records??
+ <gnu_srs> causing pflocal (and pfinet) to disappear?
+
+[[hurd/translator/mtab/discussion]].
+
+ <azeem> gnu_srs: didn't he say that this is getting fixed in his latest
+ patchset?
+ <gnu_srs> yes, what about mine and gg0s currently hosed systems?
+ <gnu_srs> yes, but until the patch makes into the next release,**
+ <youpi> gnu_srs: pflocal and pfinet don't appear in mtab
+ <youpi> because they don't expose whole directories, just a trivial node
+ <youpi> so no, they won't get umounted by umount -a
+ <youpi> simply check the content of /proc/mounts
+ <gnu_srs> so how come I cannot recover my image?
+ <gnu_srs> and gg0 neither
+ <youpi> no idea, I've never tried openrc
+ <youpi> when daring new fields, you face new issues, that's no wonder
+ <gnu_srs> so this does not happen with sysv-rc?
+ <youpi> I haven't seen any of this kind of issue
+ <youpi> whether it's related to using openrc vs sysvrc, I have no idea
+ <youpi> but at least that's a candidate for sure
+ <gnu_srs> well in my case hurd bootstrap is stuck after ext2fs exec and
+ before init
+ <gnu_srs> ant reinstalling hurd via linux does not help
+ <youpi> you mean the hurd package?
+ <youpi> you can also try to reinstall the libc0.3 package
+ <youpi> normally it should be all that is needed for boot
+ <youpi> perhaps also some /dev entries
+ <gnu_srs> yes, the hurd package. I will try with libc0.3 tomorrow. Which
+ /dev entries, and how to create them manually?
+ <youpi> "perhaps" implies that I don't know
+ <youpi> you can as well just boot with an install CD, mount your disk,
+ chroot into it, and run dpkg-reconfigure hurd there to recreate
+ everything in /dv

+ <congzhang> hi, I think we should make console server separate from
+ hurd-console
+ <congzhang> if DM want start, console server need be start first
+ <braunr> congzhang: send patches
+ <congzhang> and hurd-console mark it start at the end of sysinit?
+ <teythoon> congzhang: i agree
+ <braunr> teythoon: isn't hurd-console the console server ?
+ <congzhang> I want to check whether it is need first
+ <teythoon> braunr: yes, but congzhangs point is (as i understand it) that
+ the backend component should be started earlier
+ <teythoon> then again, i know little about the hurd console
+ <congzhang> no, if user enable one dispaly manager, then cycle dependence
+ happen
+ <braunr> why ?
+ <teythoon> i believe that is a different problem, namely that our
+ hurd-console init script depends on $all
+ <teythoon> pere: ^
+ <congzhang> hurd-console Required-Start: $all
+ <braunr> ok
+ <braunr> yes that's a separate issue, and easier to understand
+ <congzhang> teythoon: if wdm Required-Start hurd-console, then insserv
+ can't generate the script order, right ?
+ <teythoon> congzhang: possibly, i don't know for sure
+ <congzhang> It doesn't work , and I rename to S??wdm to later one like
+ S20wdm
+ <congzhang> but insserv will regenerate the script order in /etc/rc2.d/, I
+ can't depend on that
+ <pere> congzhang: $all means after all scripts not depending on $all, and
+ not what the intuitive interpretation would tell you.
+ <pere> the current implementation order all scripts as if $all were not
+ present, and then move all scripts depending on $all to the last order
+ number+1.
+ <pere> because $all is misunderstood by most users, I strongly recommend to
+ _not_ use $all in any init.d script.
+ <congzhang> pere: so to make wdm to be number+more?
+ <pere> congzhang: make it depend on $all and be lexically sorted after
+ hurd-console. :)
+ <congzhang> wdm need start after hurd-console, if console-driver will run
+ when hurd-console start
+ <pere> not quite sure how startpar handle that case, so it might not work
+ the way you want anyway.
+ <pere> adding a dependency on hurd-console should not hurt, though. :)
+ <congzhang> how make it lexically sorted after hurd-console?
+ <pere> w is already after h in the alphabet. :)
+ <congzhang> that's trick!
+ <pere> but startpar uses the info in /etc/init.d/.depend.* (makefile style)
+ to order scripts, so check what the result is there too.
+ <braunr> congzhang: no it's not
+ <congzhang> that's just cache
+ <braunr> congzhang: ?
+ <congzhang> and generated from script head?
+ <congzhang> the right way is Adding run-time dependencies in script
+ <pere> congzhang: yes. insserv called from update-rc.d generate the
+ .depend.* files, and startpar reads the files (and ignore the headers)
+ when starting scripts.
+ <congzhang> if the script have cycle dependence, no one can help
+ <pere> congzhang: if there is a cycle, update-rc.d will reject the script.
+ <congzhang> sure, because the system current have not runable one
+ <congzhang> Display Manager run before hurd-console, and never successful
+ for X stared failed!
+ <pere> what is this hurd-console stuff, btw? it sound like somthing that
+ should be started in rcboot.d (aka rcS.d on Debian).
+ <congzhang> if you install wdm, you will notice that wdm start failed
+ <pere> should it run before sulogin when booting into single user?
+ <congzhang> hurd-console mix too much thins
+ <teythoon> pere: it's the console multiplexes that provides /dev/tty?
+ <congzhang> just part of that function
+ <teythoon> pere: it's like screen or tmux a server-client architecture
+ <teythoon> the x server gets keyboard and mouse events from it iirc
+ <pere> right. so not needed by sulogin, I guess. because if it was, it
+ should start in rcS.d, not rc[2-5].d/.
+ <congzhang> and also start /bin/console to start keyboard and mouse driver
+ <teythoon> /bin/console is the frontend
+ <pere> and if it started in rcS.d/, it would always be started before
+ wdm. :)
+ <braunr> i think it should be started in rcS.d
+ <congzhang> why not essential?
+ <pere> braunr: when I tried, it failed.
+ <congzhang> https://www.gnu.org/software/hurd/hurd/console.html
+ <congzhang> teythoon: i want to make one disk img with default DM, and face
+ these problem
+ <braunr> pere: do you have a log of the failur e?
+ <congzhang> teythoon: I know you are working on the hurd init system, so I
+ ask you for help
+ <pere> braunr: only the boot message: Starting Hurd console multiplexer:
+ hurd-console failed!
+ <pere> braunr: how can I learn more?
+ <braunr> i don't know any easy way
+ <braunr> try to put the system in its early state manually
+ <braunr> and maybe run rpctrace on the actual console command
+ <braunr> if that is what really fails
+ <congzhang> and I found that pc_kbd may have some bug? I have high
+ frequence of start failed if I make it start
+ <congzhang> but I can't located the real source of these problem
+ <teythoon> pere: the console logs some messages to syslog
+ <pere> teythoon: looked, nothing there. :(
+ <pere> gah, look like I broke my hurd machine. Added rpctrace to the start
+ of hurd-console, and now the boot just hang there, and when I interrupt
+ it the kernel reboot the entire machine. :(
+ <braunr> pere: use rpctrace manually, don't script it
+ <teythoon> oh yeah, seen this as well
+ <pere> braunr: well, no use to test it after boot when it hang during
+ boot...
+ <teythoon> it triggers an assertion in the proc server iirc
+ <braunr> pere: that doesn't imply you need to script it
+ <congzhang> pere: qemu snapshot mode will be your friend:)
+ <braunr> ideally, i'd run the init system automatically up to the point i
+ want to run my test, and make it spawn a shell, and use that shell then
+ <pere> congzhang: hah. real men do to take backups. but they weep a
+ lot. :)
+ <congzhang> teythoon: runsystem.sysv has work well on my machine, just some
+ error infomation
+ <teythoon> good

+
+ <gnu_srs1> Hi, a general question: is ptrace available for GNU/Hurd?
+ <teythoon> yes
+ <gnu_srs1> tks, the openrc developers are working on process supervision
+ using it: good/bad? (compared to cgroups)
+ <teythoon> uh
+ <teythoon> i prefer the cgroups approach
+ <teythoon> but upstart also uses ptrace to keep track of the 'main' process
+ of an daemon
+ <teythoon> they use ptrace to follow a daemon that double forks
+ <gnu_srs1> teythoon: and regarding portability?
+

+
+ <braunr> sysvinit doesn't seem to handle /etc/default/locale into
+ consideration
+
+
+## IRC, OFTC, #debian-hurd, 2014-02-25
+
+ <gg0> how about switching runsystem.sysv by default?
+ <youpi> now that it seems to be running fine, we could do that, yes
