+ <youpi> I am wondering why having that
+ <youpi> since we have up-to-date mirrors
+ <gg0> i'd say to install with latest installer/gnumach/hurd/eglibc
+ <youpi> so that means also rebuilding the d-i image
+ <gg0> and in general to not have to manually produce them
+ <pere> youpi: the point is to automatically test the current images using

+ exist. :)
+ <gg0> not only. i think saving youpi's time is also important
+ <youpi> gg0: it doesn't really take me much time to generate images
+ <youpi> it's about a few command lines to start, and then work on something
+ else :)
+ <gg0> well though it still requires manual intervention which is not
+ scheduled and also error prone btw
+ <youpi> gg0: I guess the most important help you could provide would be to
+ actually track when the autobuild breaks :)
+ <gg0> what pros keeping it manual? i don't think disk space saving
+ <youpi> it's not really a question of manual, but the frequency
+ <youpi> I prefer to test manually before uploading something on my
+ somehow-official directory on people, anyway
+ <youpi> but that doesn't mean we can't have weekly builds somewhere else
+ indeed
+ <youpi> it's just that for tests it's good to have several images backlog,
+ but then it takes disk
+ <gg0> well we could keeping "official" ones + say 6 monthly and say 4
+ weekly
+ * gg0 randomizes retention
+ <gg0> -ing
+ <teythoon> gg0: check out my hurdtest program
+ <teythoon> it updates qemu images automatically, and runs a test suite,

+ <gg0> youpi: you'd just take actually care of official ones

+ <youpi> gg0: and have a cron for the others
+ <youpi> on mirror.ftp-master
+ <gg0> nice, we already have a disk image generator then

+ <youpi> I don't think that'll save me time per month
+ <youpi> since it's just an additional thing
+ <gg0> youpi: so weekly-0 will always be the latest weekly (same about
+ monthly) ?
+ <youpi> yes
+ <gg0> how about adding -YYYYMMDD after -1 CD/DVD/NETINST number?
+ <youpi> that'd mean more scripting

+ <youpi> we already have timestamps from the server

+ <youpi> what do you mean by forcing /dev/hd0s1 as root device ?
+ <youpi> you shouldn't have to do that
+ <youpi> my fear is that these additional images will mostly just bring
+ additionnal reports
+ <gg0> i had to specify it in preseed
+ <youpi> which won't really decrease the amount of work
+ <gg0> as partman-auto/disk
+ <gg0> it can recognize available disks
+ <gg0> that's also because it can't list root partitions on rescue mode
+ <youpi> well, all I can say without having (again) to spend time on it, is
+ that you're not supposed to have to do that
+ <youpi> why are you using rescue mode?
+ <youpi> if it can't list root partitions, then of course partman can't work
+ <gg0> well, rescue mode should work
+ <youpi> if you delve into non-tested parts of d-i, you'll surely encounter
+ bugs
+ <youpi> well, less "should" than plain "d-i"
+ <youpi> in that I've never really tested it
+ <youpi> so don't be surprised that some bugs remain
+ <gg0> no problem
+ <youpi> but again, we don't really need more bug reports
+ <youpi> but rather bug fixing
+ <youpi> we already have enough to fix, no need to delve into advanced
+ things
+ <gg0> sure, i'm just trying to make it work with all its limitations
+ <gg0> it autopartition the disk well, it can't just make one choose among
+ disks because it can't probe and list them
+ <youpi> then fix the probe & list
+ <gg0> i'd like doing it, i'm better at working around for now though :)
+ <gg0> one blocker is mount/umount stuff
+
+[[glibc#mount]].
+
+ <youpi> well, you'll have to get into fixing bugs for real someday
+ <youpi> otherwise this is just adding to TODO lists
+ <youpi> what mount/umount stuff?
+ <gg0> (took a quick look at partconf)
+ <gg0> non-existent mount.h for instance
+ <gg0> do we have replacements?
+ <youpi> not that I know of
+ <gg0> 21:53 < teythoon> gnu_srs1: i put a small hacks entry in the list
+ about moving the mount/umount functionality from our utilities to the
+ libc
+ <youpi> ok
+ <gg0> another thing i'd really like to see would be a physical shutdown,
+ halt-hurd which actually poweroffs the system
+ <gg0> how to switch to sysvinit by default? next sysvinit upload?
+ <youpi> physical shutdown means implementing APM or ACPI
+ <gg0> have to teach jenkins it can shut it down :/
+ <youpi> I'm extremely far from having the will for this
+ <youpi> switching to sysvinit by default is a matter of saying that we want
+ to do it
+ <youpi> I already asked for this on the list without answer IIRC
+ <gg0> i can't find anything
+ <youpi> anyway, just propose on the list
+ <gg0> d-i grub-installer/bootdev string /dev/hd0 - here it is
+ <gg0> next run should not need any interaction, though it needs 20 mins to
+ understand it has to destroy it and run won't be successful :/
+ <gg0> due to missing acpi/apm
+ <gg0> first graphical automated install http://postimg.org/image/vgagj06q7/
+ <gg0> it seems 720x400
+ <gg0> though jenkins passes video=vesa:ywrap,mtrr vga=788
+ <gg0> by reconnecting it switched to 800x600
+ http://postimg.org/image/h32qjykrx/
+ <gg0> but seems stuck now and i can't even switch from graphical to
+ consoles
+ <gg0> unusually stuck at scanning cdrom
+ <gg0> i'll check text install to see if it gets stuck there too
+ <gg0> text install switches from 720x400 to 640x400
+ <gg0> i confirm it gets stuck on scanning cdrom, i guess because of this
+ one https://bugs.debian.org/728153 which already broke load-install-cd i
+ already had to workaround
+ <pere> gg0: are you in contact with h01ger to update jenkins.debian.net
+ with your cool installation code?
+ <gg0> pere: still trying to have something working
+ <gg0> plus with new weekly cd, apt-cdrom bug makes install getting stuck at

+ <gg0> 03:44 < gg0> i confirm it gets stuck on scanning cdrom, i guess
+ because of this one https://bugs.debian.org/728153 which already broke
+ load-install-cd i already had to workaround
+ <youpi> do we really need the CD-1 image in weekly builds?
+ <gg0> just netinst?
+ <youpi> yes
+ <gg0> well, i don't know debian installer well. what's the difference
+ between CD and NETINST besides that CD has more packages user doesn't
+ need to download?
+ <gg0> has CD anything not in NETINST which is worth to continously test?
+ (talking about jenkins)
+ <youpi> that's only it, yes
+ <gg0> btw new ACPI on hurd consists of serial console to file + looping
+ grep "In tight loop: hit ctl-alt-del to reboot" && kill qemu
+ <gg0> anything better?
+ <gg0> filed http://bugs.debian.org/740673
+ <gg0> without a patch just to express my great laziness :p
+ <youpi> well, I'm afraid nobody in the debian-boot team will attempt
+ anything at this
+ <youpi> is it reproducible on linux?
+ <gg0> nope
+ <gg0> my guess is that's due to udev, need a deeper check btw
+ <gg0> i mean non-udev cases like hurd maybe are not handled well
+ <youpi> maybe try on kfreebsd then?
+ <gg0> just guessing
+ * gg0 trying on kfreebsd

+
+ <gg0> hurd install started getting stuck running os-prober, final grub
+ install phase
+ <gg0> youpi: yes i confirm it affects kfreebsd too
+ <youpi> then please say so in the bug
+ <youpi> otherwise most probably but me in the debian-boot team will care
+ <youpi> +nobody
+ <gg0> that might get more attention from d-boot team?
+ <gg0> ok
+ <youpi> also Cc debian-bsd@
+ <youpi> they will care
+ <youpi> and tell about the hint as being the non-udev case
+ <youpi> too much information or ideas is never a bad thing :)
+ <gg0> done
+ <gg0> (now i know notfound does remove found versions instead of adding
+ notfound versions)
+ <gg0> crazy things. to unblock os-prober i had to settrans -fg
+ /target/media/./cdrom0
+ <gg0> it was mounting /dev/hd0s1 ...
+ <gg0> i suspect apt-cdrom is to blame again
+ <gg0> ok now jenkins just managed to start the installed system
+ <gg0> and it's configured to make vncdo testing it
+ <gg0> i'd need a graphical-working cd with old-apt to continue
+ <gg0> let's try to install old apt on weekly-0
+ <gg0> "cdrom drive contains a cd which cannot be used for installation"
+ <gg0> i think a sort of non-authenticated anymore
+ <gg0> ehm.. http://paste.debian.net/plain/85224/
+ <pere> gg0: nice. :)
+ <gg0> with apt 0.9.15.1 which should be good
+ <gg0> pere: it did mount /dev/hd0s1 under /media/cdrom0
+ <gg0> 0.9.15.5, correctly i think, asks to insert it cdrom. but finally
+ both mount /dev/hd0s1 instead of /dev/hd2
+ <gg0> -it
+ <gg0> cause they both can't detect where cdrom is i guess
+
+
+## IRC, freenode, #hurd, 2014-03-04
+
+ <gg0> we could talk about apt-cdrom https://bugs.debian.org/740673
+ <gg0> how should system recognize cdrom device?
+ <gg0> there's no /dev/cdrom link to actual cdrom device
+ <gg0> /dev/cd[01] are scsi devices if i'm not wrong

+ <gg0> installer gets stuck running os-prober, seems because
+ /target/proc/mounts gets unreadable, sometimes Resource lost sometimes it
+ gets stuck reading it
+
+[[hurd/translator/mtab/discussion#chroot]].
+
+ <gg0> youpi: could you publish script to rebuild CDs you scheduled? with
+ last official CD (20140212) mtab on /target dies and that seems getting
+ os-prober stuck. last (and only) weekly has recent apt-cdrom so it gets
+ stuck wrongly asking to change cdrom
+ <youpi> see the readme file
+ <youpi> err, you say it's the 0212 build which fails?
+ <youpi> I had tested that before uploading
+ <youpi> so the issue comes form the installed packages, not from the CD
+ udebs
+ <youpi> did you test with no network mirror?
+ <gg0> no i didn't. should it find all packages it needs from cd?
+ <youpi> sure, that's what netinst and dvd-1 are, as opposed to netboot
+ <gg0> lxde desktop probably not
+ <youpi> indeed
+ <youpi> though with the dvd in principle it should
+ <youpi> (if all deps were avaijlable at image build time)
+ <youpi> gg0: btw if you haven't noticed, there's a daily too
+ <gg0> youpi: till apt-cdrom is not fixed, they all will be broken, stuck at
+ "Scanning cdrom"
+ <youpi> gg0: did you try to bisect which git change produces the apt-cdrom
+ bug?
+ <gg0> youpi: all in bug in question
+ <gg0> youpi: https://bugs.debian.org/740673
+ <youpi> is there the precise git commit id in the bug log?
+ <gg0>
+ http://anonscm.debian.org/gitweb/?p=apt/apt.git;a=commitdiff;h=62dcbf84c4aee8cb01e40c594d4c7f3a23b64836
+ <youpi> well, don't tell that to just me, but the bug report...
+ <gg0> bug report says "See <bug>" where bug is
+ https://bugs.debian.org/728153
+ <youpi> gg0: bug report doesn't say it was *tested* that it is that changes
+ which broke things
+ <gg0> i don't think we could get it reverted just because it breaks hurd
+ (+kfreebsd to check) debian installer
+ <youpi> of course, but that's at least where developers can have a look at
+ <gg0> well ok i could have been more clear
+ <youpi> it's *WAY* better than having no idea where to have a look at
+ <youpi> gg0: btw, that's why the README file advises not to use a network
+ mirror, to avoid such kind of issues
+ <youpi> you can't expect sid not to be not-broken :)
+ <gg0> one gets Resource lost even when install is just started, no packages
+ from any mirror
+ <gg0> https://bugs.debian.org/740673#19
+
+ * gg0 installing without mirrors, without desktop, without lxde
+ <gg0> same problem
+ <gg0> so problem has nothing to do with installing from mirrors
+ <youpi> what's odd is that I don't get this issue at all with the 20140212
+ upload at least
+ <youpi> kvm -cdrom debian-7.0-hurd-i386-NETINST-1.iso -drive
+ file=blip,cache=unsafe -m 1G
+ <youpi> no more, no less
+ <gg0> it must depend on preseed and/or kernel append options
+ <youpi> possibly
+ <gg0> oh wait here qemu multiboot
+ <youpi> that shouldn't have any impact
+ <youpi> did you leave the command line somewhere on the wiki so I can try
+ with it, just to be sure?
+ <gg0>
+ http://darnassus.sceen.net/~hurd-web/hurd/running/qemu/#QEMU_Multiboot
+ <gg0> 5€ on qemu multiboot as the culprit
+ <gg0> you should also see it sometimes double-mounts /dev/hd0s1 under
+ /target and /target/./media/cdrom(!)
+ <gg0> but that's due to new apt it in-targets (= installs under /target)
+ <youpi> gg0: rather use the gnumach, ld.so and ext2fs.static from the ISO
+ image you are booting
+ <youpi> especially for ld.so, which has to be the same as the libc
+ installed in the initrd
+ <youpi> ah, you're getting the initrd there too
+ <youpi> well, really use the same as the ISO
+ <gg0> i already do
+ <youpi> ah, ok, so the wiki example is just with current
+ <youpi> but the wiki example doesn't use -cdrom to provide the ISO ?
+ <gg0> no it doesn't even mention you could also use a cdrom
+ <gg0> it just shows how to use qemu multiboot options
+ <youpi> it seems one have to avoid any blanks in the multiboot option
+ <youpi> notably before file names
+ <gg0> well, actually it works but it's rather incomplete
+ <youpi> well, it shows how to boot the installer
+ <youpi> not how to boot an installed system
+ <gg0> removed spaces, added <other_qemu_options> option
+ <gg0> here qemu binary is qemu-system-x86_64 instead of qemu-kvm and it
+ crashes without --enable-kvm
+ <gg0> qemu: fatal: Trying to execute code outside RAM or ROM at
+ 0x000000010010001e
+ <youpi> rather use qemu-system-i386
+ <gg0> i was just complaining i wrote qemu-kvm on wiki but i did never
+ actually run that command as is
+ <gg0> ouch right, -i386 doesn't require enable-kvm
+ <gg0> (i'll never know why)
+ <youpi> -x86_64 is buggued
+ <youpi> 0x000000010010001e should have been truncated to 0x0010001e since

+ <gg0> i should provide preseed too

+ <gg0> not much different from
+ http://jenkins.debian.net/d-i-preseed-cfgs/debian_sid_daily_lxde_preseed.cfg
+ <gg0> but you need to force a couple of things + ugly workaround for broken

+ <youpi> well, I didn't even know that jenkins had that pressed file
+ <youpi> well, here apt-cdrom is not needed
+ <youpi> +hacks
+ <youpi> since that's the old image we're checking
+ <gg0> well ok, given you take everything from cd only, yes
+ <gg0> here no mirror, no desktop, no lxde
+ http://paste.debian.net/plain/85538/
+ <gg0> i'm trying this one too
+ <gg0> main difference seems to be i usually use CD-1, not NETINST
+ <gg0> had to add -net nic,vlan=0 -net
+ user,vlan=0,host=10.0.2.1,dhcpstart=10.0.2.2,dns=10.0.2.254
+ <gg0> here target mtab is already crashed

+ <gg0> youpi: reproduced there?
+ <gg0> .o(well, maybe he's been sleeping for ~50 mins)
+ <youpi> nope, I'm working on upgrading servers
+ <youpi> I'm sorry, but your testcase is not really easy to reproduce :)
+ <gg0> do you have apache on your host? just put preseed in the root, vm
+ will take it
+ <gg0> full command line is what you pasted + -net nic,vlan=0 -net
+ user,vlan=0,host=10.0.2.1,dhcpstart=10.0.2.2,dns=10.0.2.254
+ <gg0> what else? when it starts debstrapping, open a console and check
+ procfs and mtab processes
+ <gg0> err, what you paster + -append i pasted + -net nic,vlan=0 -net
+ user,vlan=0,host=10.0.2.1,dhcpstart=10.0.2.2,dns=10.0.2.254
+ <gg0> *pasted
+ <gg0> which is http://paste.debian.net/plain/85554/
+ <gg0> surely keyboard layout doesn't help, here at least
+ * gg0 tries to reproduce without preseed
+ <gg0> i can't reproduce it
+ <gg0> it doesn't crash
+ * gg0 enabling all options but preseed
+ <gg0> need to wait 31% of Installing base system to have the second procfs
+ <gg0> ok got Resource lost even without preseed
+ <gg0> youpi: you can reproduce it by adding -append console=com0 to what
+ you pasted. that breaks grub-installer, it gets stuck at 66%, while runs
+ os-prober
+ <youpi> ah
+ <gg0> how can that affect /target/proc/mounts?
+ <youpi> no idea
+ <gg0> couldn't daily be here? http://d-i.debian.org/daily-images/
+ <youpi> if I knew how to push files there, sure
+ <gg0> asking on #debian-boot would be a starting point i guess
+ <youpi> probably
+ <gg0> me asking on behalf of youpi would not a good one i think, given

+ <youpi> you can still trasmit me
+ <youpi> never understimate the little time you can save other people by

+ <gg0> well, i would not even have to repaste lines here given you joined
+ there too
+ <gg0> never understimate what "help with laziness" means :)
+ <youpi> not necessarily repasting, but at least highlighting me
+ <youpi> so I know where to read in the #d-b logs
+ <gg0> there are no isos there, i'm missing something
+ <youpi> there are no daily isos

+ <gg0> oh just realized it's not only under a chroot, chroot is on another

+ <gg0> i didn't try to reproduce it by creating a chroot on a different
+ disk, which is what installer does
+ * gg0 wonders if it would have been better filing a bug against
+ cdimage.debian.org
+ <gg0> if no one fixes console=com0 thing, i have to think about a new acpi
+ <gg0> ok managed to workaround apt bug in installer, i can graphically
+ install last weekly
+ <gg0> no console=com0 means no vm shutdown though
+ <pere> gg0: wow. impressed!
+ <gg0> patching CI to make CI workaround bugs CI spots is not so good
+ <gg0> any idea about another shutdown trick without console=com0 till
+ teythoon or youpi fix it?
+ <pere> nope
+ <gg0> current one: vm writes serial console to file and host loops grepping
+ "In tight loop: hit ctl-alt-del to reboot"
+ <gg0> -watchdog might be an alternative
+ <gg0> if there are watchdog agents that can run on hurd

+ <gg0> i was under /root, sid-chroot is the mountpoint. i did mount /dev/hd3
+ sid-chroot (relative path)
+ <braunr> does fsysopts confirm a new translator is running on sid-chroot ?
+ <gg0> i shut down vm, working on another one by mounting the same disk

+ <gg0> i'm trying to reproduce the mtab-dying-on-chroot issue i get with

+ <gg0> at the end, os-prober gets stuck by reading /target/proc/mounts
+ (target is the installed system)
+ <gg0> to be precise it gets stuck at second access. at first it gives

+ <gg0> environment is pretty the same: booting with qemu multiboot

+ <gg0> youpi: from #debian-cd http://paste.debian.net/plainh/559f669b
+ <gg0> any quick way to recreate initrd?
+ <teythoon> gg0: i'm working on that
+ <gg0> teythoon: that what?
+ <teythoon> gg0: there is genext2fs, i have some patches that allows one to
+ create nodes with passive translator records
+ <gg0> recreating initrd?
+ <teythoon> yes
+ <teythoon> in the meantime, you can mount the existing initrd and modify it
+ <gg0> well i'm following this one to rebuild whole cd then take an updated
+ initrd to test with your repo
+ <gg0> http://people.debian.org/~sthibault/hurd-i386/installer/README-d-i
+ <gg0> probably too much work to get that
+ <gg0> copying current /hurd to new initrd would be enough?
+ <youpi> just copy the precise translator you need
+ <youpi> also, no need to rebuild the whole cd just to replace the initrd
+ <youpi> simply copy the content of an existing is
+ <youpi> iso
+ <youpi> replace the initrd.gz there
+ <youpi> and then use grub-mkrescue to rebuild the ios
+ <youpi> development would be horrible if you had to rebuild everything from
+ zero everytime
+ <youpi> first thing to do when developping is first take the time to find
+ ways to work efficiently
+ <gg0> i'd want to try multiboot with teythoon's gnumach/hurd but boot gets
+ stuck with old initrd
+ <youpi> unfortunately I had to apply some patches
+ <youpi> first in d-i because isc-dhcp doens't work -> use the debian-ports
+ version
+ <gg0> so i could simply copying whole /hurd dir to new initrd
+ <gg0> -ing
+ <youpi> then in d-i to automatically enable the debian-ports mirror
+ <youpi> and last in the debian-cd to include debian-ports-archive-keyring
+ <youpi> you'd also need to copy the libs
+ <gg0> anything missing here?
+ http://people.debian.org/~sthibault/hurd-i386/installer/README-d-i
+ <gg0> libc0.3 on initrd is still 2.17
+ <gg0> mini.iso doesn't like any mirror
+ <gg0> "mirror does not support the specified release"
+ <gg0> something wrong/missing in my rebuilt
+ <gg0> youpi: anything wrong in http://paste.debian.net/plain/86258 ?
+ <gg0> i have/had problems with name resolution
+ <youpi> gg0: the patch makes sense for -bsd too, Cc them too
+ <gg0> i was wondering how many hunks in your patches are upstreamable
+ <youpi> normally it's zero
+ <gg0>
+ http://people.debian.org/~sthibault/hurd-i386/installer/patch-debootstrap
+ <gg0> why "release" instead on "main" by default? sid is never released
+ <youpi> only because my mirror directory is hacked one
+ <youpi> that merges debian.org, debian-ports.org, and my repo
+ <youpi> and I don't rebuild Release files, just Packages files
+ <gg0> i keep getting gpgv: BAD signature from "Debian Archive Automatic

+ <gg0> just before creating debootstrap chroot
+ <gg0> i applied hunk #2 only, installed modified debootstrap and put debs
+ under localdebs/
+ <gg0> trying a different mirror
+ <youpi> I don't know what issue you are encountering
+ <youpi> but again, it's way simpler and faster to just patch existing
+ images, rather than rebuilding them from zero
+ <gg0> ok just read i'd need a local mirror to build isos
+ <gg0> better using netinst and proxy cache

+ <teythoon> but there are two programs, that are not started using the exec
+ server
+ <teythoon> the root filesystem and the exec server itself
+ <teythoon> so for these two processes, the approach does not work
+ <gg0> i see. so here we got two which could come from
+ ext2fs.static(initrd), exec(initrd) and ext2fs(chroot)
+ http://postimg.org/image/e3qyafd0b/ right?
+ <gg0> i also noticed that once mtab dies, by killing its procfs parent,
+ they both restart, but /target/proc is not in /proc/mounts anymore
+ <youpi> teythoon: for those we could use the first word of the module
+ command line
+ <gg0> restart doesn't means that by accessing /target/proc/mounts again it
+ works btw, it'll give Resource lost again
+ <teythoon> youpi: indeed
+ <teythoon> gg0: no, the ext2fs for /target will be started by the exec
+ server
+ <gg0> ok two invalid ports one from ext2fs.static and one exec then
+ <teythoon> gg0: what makes you attribute one to the exec server ?
+ <teythoon> i'm pretty sure that there is a bug in libfshelp, it's easily
+ triggered by killing an translator like procfs
+ <teythoon> i must have introduced it with the translator list work i've
+ done for the mtab translator
+ <gg0> teythoon: a totally wrong task-is-a-process reasoning probably
+ <gg0> just mounted another procfs which seems to work
+ <gg0> http://postimg.org/image/q6w9xzo2j/
+ http://postimg.org/image/cr998jfkr/
+ <teythoon> gg0: the mtab translators in your screenshots are oldish, what's
+ the point exactly ?
+ <teythoon> gg0: also, all tasks are processes. task is a mach concept,
+ whereas process is a posix concept implemented by hurds proc server. it
+ creates a process object for every mach task.
+ <gg0> my guess was that given we got two messages with different taskid:
+ <gg0> 16:01 < gg0> ok two invalid ports one from ext2fs.static and one exec
+ then
+ <gg0> screenshot is this one http://postimg.org/image/e3qyafd0b/

+ <braunr> on a machine that provides nested page tables, this makes the

+ <braunr> hugetlbs reduces the overhead of page faults, and also implies
