## Hurd Debian-Installer
My [proposal](http://wiki.debian.org/SummerOfCode2010/HurdDebianInstaller/JeremieKoenig)
to work on porting d-i on Hurd
as a [Google Summer of Code](http://code.google.com/soc/) student
has been accepted by the Debian project.
I will be keeping track of my progress on this page.

### Roadmap
* **mach**: initrd support
* (./) preliminary patch posted and self-built (2010-06-12)
* adjustments will be needed (postponed)
* consider the alternatives discussed on bug-hurd (postponed)
* **glibc**: fix `mkdir("/")` which returned `EINVAL`
* (./) eglibc 2.11.2-1 includes a quick fix by youpi (2010-06-15)
* (./) more complete patch posted to bug-hurd,
since other calls return incorrect errors under some circumstances
(2010-06-16)
* more work on it will be needed to make it fix the whole thing
(postponed)
* (./) **partman** (2010-06-23)
* (./) add hurd-i386 to
`partman-partitioning/lib/disk-label.sh`
(2010-06-16, commited by youpi on 2010-06-23)
* (./) short-circuit
`partman-basicfilesystems/init.d/kernelmodules_basicfilesystems`
(2010-06-16)
* (./) partman-auto recipes:
make the default filesystem os-dependent
when it has not been preseeded (ie. the *seen* flag is clear)
* (./) force 4k blocks and 128 bytes inodes
* (./) submit patches to bugs.debian.org
([[!debbug 586870]] and [[!debbug 586871]])
* (./) rebuild with responsible version numbers and upload to my repository
* (./) **libparted** (2010-06-23)
* (./) fix device paths ([[!debbug 586696]])
* (./) fix crash on exit for part:* stores ([[!debbug 586682]])
* **hurd-udeb** (2010-06-23)
* (./) rebuild with the hack suggested by youpi for qemu network configuration
* (./) fix mount to accept `-o defaults`
* cleanup, ask youpi to commit
* reloading the partition table (2010-06-25)
* User-space part stores
* (./) hurd-udeb now uses `part:N:device:X` for partition devices
(2010-06-23)
* (./) it also provides /lib/partman/commit.d/??hurd\_reloadpart,
which basically does `settrans -ag /dev/[hs]d*`.
(2010-06-24)
* Kernel-based partition devices
* (./) Mach's drivers from Linux support reloading partitions.
With help from youpi this has been made available through a
device\_set\_status() call.
* (./) make libparted use it
* Reminder:
I should file a bug against libparted with the patch sometime.
* (./) The `/servers/exec` issue (2010-06-26)
* Due to /servers being inexistant,
the bootstrap ext2fs could not register the initial exec server,
meaning that non-bootstrap filesystems used a different one
(started from the passive translator),
which for some reason died on shell scripts, making them stall.
* Adding the `/servers` directory to hurd-udeb fixed it,
as well as the /hurd/proc issue
(failed to be run by init the first time around).
* Reminder: report the non-bootstrap exec servers failure on scripts.
* (./) **base-installer**: (2010-06-26)
* Work around non-existant /proc/mounts.
* Firmlink /servers into /target after debootstrap
to make the network available.
* (./) **grub-installer**
* (./) add hurd support (2010-06-27)
* /!\ grub-legacy still needs to be tested
* submit changes as a Debian bug
**Milestone (2010-06-28):
installer kindof works, with documented manual intervention required**
* (./) Sort out the situation with dev node creation (2010-07-07):
* Devices and servers used to be set up by debootstrap;
the hurd package would add some missing nodes.
* New strategy implemented in hurd and debootstrap:
* debootstrap uses active firmlinks into the host system
for the target system's /dev and /servers.
* the hurd package now include a `setup-translators` script,
which is used to register the passive translators by the installer's
`/libexec/runsystem` and hurd's postinst script.
* **busybox**: submit upstream and to [[!debbug 323670]]
(waiting for upstream to review)
* (./) I have mentioned my work on the upstream mailing list,
* (./) merge the recent changes from upstream,
notably to the build system.
(2010-06-23)
* (./) ask upstream for review and merge
(2010-06-25)
* (./) sent as patches as requested
(2010-07-08)
* (./) backport any additional changes onto the debian branch
* (./) hijack [[!debbug 323670]] and submit my patches
* **aptitude**:
* Currently broken on hurd-i386:
[[!debpkg gtest]] fails to build because of a segfault in one of the test
cases, [[!debpkg google-mock]] and hence [[!debpkg aptitude]] are missing
it as a build-dep.
The older package is not installable anymore because it's linked against
an older version of libept, which has been removed.
* (./) I bypassed the tests and uploaded the 3 packages to my repository
(2010-07-08)
* The segfault will have to be sorted out. (postponed)
* (./) "Fix" the swap situation. (2010-07-08)
* The device\_close() libstore patch
had the unfortunate effect of making swapon fail,
since the device it activates has to be kept open.
* add options for MAKEDEV and setup-devices
to use the libparted stores
* disable youpi's patch
* make partman-basicfilesystems re-create the device
as a kernel partition, which is needed for swapon
* (./) netcfg-static: port to hurd (2010-07-09)
* There was some amount of hurd support already
(namely, activating the interface by replacing the socket translator)
* However, this code started an active translator with
di\_exec\_shell\_log("settrans -a ...),
which stalled as a consequence of it capturing libdi's pipe
as its standard output.
* Network devices must be probed by trying to open Mach devices
with predetermined names (currently eth%d, wl%d),
because getifaddrs() does not seem to work on Hurd.
* /!\ netcfg, and configuring the installed system, postponed.
* **procps** 3.2.7-11 (current hurd-i386 version) has [[!debbug 546888]]
* (./) Submit [[!debbug 588677]] and upload the result to my repository.
(2010-07-11)
* (./) Set up a Debian mirror with modified packages for installation
* the [mirror](http://jk.fr.eu.org/debian/hurd-install/mirror)
is now up and running (2010-07-06)
* hacked the image build script to include its public key in
debian-archive-keyring at image build time (2010-07-08)
* Apparently debootstrap does not handle multiple versions very well.
Fix by using dpkg-scan{package,sources} rather than apt-ftparchive
to create index files.
(2010-07-10)
* Use the override files from ftp.debian.org,
to avoid debootstrap grabbing inappropriate packages.
* Changed them to make [[!debpkg ifupdown]],
[[!debpkg dhcp3-client]] and [[!debpkg dhcp3-client]] priority extra,
because they're uninstallable at the moment.
(2010-07-12)
* (./) Put together a "jk-archive-keyring" package,
so that the mirror is authenticated in the target system as well.
(2010-07-12)
* (./) Fix grub for user-space partitions (2010-07-16)
* grub-probe detects the whole device rather than the partition
as the device behind /boot/grub.
Consequently, grub-install fails.
* One approach would be to replace /dev/hd* by kernel devices
for file systems as well as for swap partitions.
> {X} this makes the installer crash,
> possibly due to cache coherency issue between hdX and hdXsY.
* (./) GRUB2 kern/emu/getroot.c
[patched](http://lists.gnu.org/archive/html/bug-hurd/2010-07/msg00059.html)
to support part stores.
* (./) Fix finish-install to skip `finish-install.d/90console` on Hurd
(2010-07-17)
* (./) Avoid starting unnecessary /dev translators in a burst (2010-07-20)
* Use debootstrap use the extracted /usr/lib/hurd/setup-translators
to create device and server nodes in /target,
then firmlink the whole /target/dev and /target/servers
to the outer system.
* Make hurd.postinst not touch them on initial install.
* (./) Fix mach-defpager for file and part stores on larger devices
* Use DEVICE\_GET\_RECORDS instead of DEVICE\_GET\_SIZE, which overflows an int
(2010-07-22)
**Milestone (2010-07-22):
installer works but it's still somewhat ugly and broken**
* (./) Ship the UTF-8 font for the hurd console
(2010-07-22)
* Upload a version of bogl with youpi's patch for Hurd.
(see [[!debbug 589987]])
* Fix the hurd console for fonts with 16 pixels wide glyphs
(ie. handle the 8-wide glyph in there correclty)
* Support double-width glyphs (2010-07-24)
* (./) However the reduced font can't be loaded yet,
so make installer/build/Makefile
ship the whole `/usr/src/unifont.bgf`
as `/usr/share/hurd/vga-system.bgf`.
* (./) Make the installer used the extended capabilities of the Hurd console
(2010-07-23)
* Set an UTF-8 locale in `/lib/debian-installer.d/S41term-hurd`.
* localechooser: set the language display level to 3
when using the hurd console.
* (./) **busybox**: cross-platform package uploaded to experimental
(2010-08-03?)
* Aurelien Jarno updated the packaging to busybox 1.17.1,
fixed a whole lot of bugs,
and uploaded a new package with both our changes;
* most patches adopted upstream, and included in the new package;
* (u)mount/swaponoff ported to kFreeBSD;
* per-OS configuration overrides.
* (./) Update custom packages to the latest versions
and send updated patches to the BTS
(2010-08-11)
* updated partman-base to choose a default filesystem in debian/rules
rather than at runtime,
as suggested by Aurelien Jarno in [[!debbug 586870]]
* patch submitted for debian-installer-utils
([[!debbug 592684]]).
* patch submitted for locale-chooser
([[!debbug 592690]]).
* debootstrap, grub-installer and finish-install not yet submitted,
since the details may still change.
* (./) **partman-target**: fix fstab creation
(2010-08-11)
* See [[!debbug 592671]]
* debian/rules: set `partman/mount_style` to `traditional` on Hurd.
* finish.d/create\_fstab\_header: add a Hurd case.
* (./) **rootskel**: FTBFS on Hurd and other quirks
(to be fixed very soon)
* **d-i/installer/build**: (expected soon)
* publish the patch I use
* sort out the changes suitable for inclusion
and ask youpi and/or debian-boot@l.d.o to commit them
* call for testing and fix the bugs
* Bug in setup-translators/MAKEDEV:
permissions are broken for nodes re-created through `MAKEDEV -k`,
because MAKEDEV's chmod/chown reaches the pre-existing translator
* Maybe settrans could be made to accept -o/--owner and
-p/--perm, to set the permissions for the underlying node?
* (./) Silence the "no kernel" warning somehow.
* Investigate the wget/libc/pfinet/whatever bug which corrupts Packages.gz,
see the IRC log for 2010-07-23, around 1am UTC+0200
* Try to resolve problems with udebs which are uninstallable on hurd-i386,
such as installation-locale and partman-whatever.
* Provide `/proc/cmdline -> 2/cmdline`, or something.
* Prepare a NMU for genext2fs (which is orphaned),
and ask youpi to sponsor the upload.
* **busybox**: port
* fix stty/stat/ipcs on kFreeBSD,
* generally port more stuff,
* *ip* is needed (maybe) for network configuration,
* *mount*, *swaponoff* can be from hurd-udeb for now,
though the kFreeBSD people will need them
* **partman**: further adjustments
* partman-base: handle /dev/hd?s* in lib/base.h
* hide irrelevant mount options? (sync, relatime)
* Network configuration on the installed system.
This includes porting ifupdown and isc-dhcp-client,
which are currently uninstallable on hurd-i386.
* Also, better DHCP support during and after installation
* improve the [initrd situation](FIXME: link to bug-hurd post):
ajust the ramdisk support in Mach,
use tmpfs if possible.
* mklibs{,-copy}:
test library reduction,
make it copy the ld.so -> ld.so.1 symlink.
* (./) hurd console fonts
**Milestone (expected 2010-07-19):
it works great and it's beautiful**
* test, fix, document
* support more types of installation images
* give a shot at the graphical installer if time permits
* integrate wireless drivers with netcfg
* see how [[zhengda]]'s work on DDE could be integrated
* etc..
### Mostly done
#### Week 1 (2010-05-24)
* genext2fs: patches submitted, [[!debbug 562999]]
which add support for all block sizes and choosing them at runtime.
* busybox: started porting the upstream and Debian package to Hurd and FreeBSD
* rebuilding hurd-udeb from the pkg-hurd version
and adding a ld.so link to the initrd
fixes the exec translator crashing on startup.
(BTW would there be a mean to detect this from the libdiskfs bootstrap code
and report it ?)
#### Week 2 (2010-05-31 to 2010-06-06)
* *busybox*: patches [posted](http://lists.debian.org/debian-bsd/2010/05/msg00048.html).
* *libdebian-installer4*: [[!debbug 584538]]
* started working on mach initrd support
* the installation images could boot into the main-menu
with the following changes:
* rebuild hurd-udeb from with the latest pkg-hurd patches
* use busybox from my osports-debian branch (see link above)
* tweak the d-i image build scripts
* the symlink /lib/ld.so -> ld.so.1 needs to be created somehow
(youpi mentionned it being the job of libc0.3-udeb I think)
* fix the poll() issue in libdebian-installer
(patch to be submitted soon),
also there is some hurd doxygen short-circuiting stuff
there which does not apply any more and prevents is to build.
* feed the initrd as a hard drive in qemu
(with some more space added to avoid it from becoming full)
