## 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.

### Latest news

  * current status:
    [busybox](http://lists.debian.org/debian-bsd/2010/05/msg00048.html),
    [genext2fs](http://bugs.debian.org/562999),
    [libdebian-installer](http://bugs.debian.org/584538) and
    [gnumach initrd](http://lists.gnu.org/archive/html/bug-hurd/2010-06/msg00047.html)
    have been worked on;
  * [modified packages](http://jk.fr.eu.org/debian/unstable) and
    [images](http://jk.fr.eu.org/debian/hurd-installer) published.

### 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**
    * (./) add hurd-i386 to
      `partman-partitioning/lib/disk-label.sh`
      (2010-06-16)
    * (./) 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)
    * rebuild with responsible version numbers and upload to my repository
    * submit patches to bugs.debian.org
      (expected 2010-06-17)

* **libparted**: fix device paths (expected 2010-06-17)
    * one-char-er patch to be tested real soon
    * submit to bugs.debian.org

* **mach**/**libparted**: reloading the partition table (unsure, urgent)
    * unfortunately, *non-workable-aroud* without a reboot
    * rumour has it that there is some support in mach,
      we need to coordinate that with userspace
    * rumour has it that there is some code to handle partitions in userspace
      with libparted, might be interesting as well

* **d-i/installer/build**: (expected 2010-06-19)
    * 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

* **hurd-udeb**: (expected 2010-06-19)
    * rebuild with the hack suggested by youpi for qemu network configuration
    * cleanup, ask youpi to commit

* **busybox**: submit upstream and to [[!debbug 323670]] (expected 2010-06-20)
    * (./) I have mentioned my work on the upstream mailing list,
    * merge the recent changes from upstream,
      notably to the build system.
    * ask upstream for review and merge
    * backport any additional changes onto the debian branch
    * hijack [[!debbug 323670]] and submit my patches

*Milestone (expected 2010-06-21):
installer kindof works, with documented manual intervention required*

* **partman**: further adjustments
    * force 4k blocks in every case
    * hide irrelevant mount options? (sync, relatime)

* **busybox**: port 
    * fix stty/stat/ipcs on kFreeBSD,
    * generally port more stuff,
    * *ip* is needed for network configuration,
    * *mount*, *swaponoff* can be from hurd-udeb for now,
      though the kFreeBSD people will need them

* tweak the hurd debian package to handle
  what native-install used to be required for
  [apparently there's already some relevant stuff done in the postinst,
  it might just work though maybe something is missing,
  or some special code would be needed in the installer
  to enable say, /servers/socket/local before anything
  is attempted in the chroot]

* investigate the /hurd/proc issue

* netcfg: make it work on Hurd somehow (port `busybox ip`?)

* Hurd-specific partitionning (use supported fs types and options).
  NB: we will need support in mach to reload the partition tables,
  or alternatively use the parted support in libstore somehow.

* grub2 installation

*Milestone (expected 2010-07-05):
installer works but it's still somewhat ugly and broken*

* call for testing and fix the bugs
* improve the [initrd situation](FIXME: link to bug-hurd post):
  ajust the ramdisk support in Mach,
  use tmpfs if possible,
  possibly add `module -nounzip` to grub2.
* mklibs{,-copy}:
  test library reduction,
  make it copy the ld.so -> ld.so.1 symlink.
* hurd console fonts
* better DHCP support during and after installation

*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
* see how [[zhengda]]'s work on DDE could be integrated
* etc..

### Mostly done

#### Week 1 (2010-05-24)

* genext2fs: patches [submitted](http://bugs.debian.org/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*: [ditto](http://bugs.debian.org/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)
