Debian > Debian GNU > Debian GNU/Hurd

This page attempts to be a reference for all resources related to Debian GNU/Hurd that can be useful for users and developers. Feel free to add more stuff as you see fit.

"In a discussion with the Debian Hurd porters it was decided that the Hurd port stays on FTPMaster until Wheezy is released. Should they have managed to get the port into a state that it is released together with all the others (probably as a technology preview), it is kept in the archive. Should they not manage this the port will be removed from the main archive and move fully to debian-ports.org."¹

What is Debian GNU/Hurd ?

Debian GNU/Hurd is an operating system from Debian, but which uses GNU Hurd, which a set of servers, running on top of the GNU Mach microkernel instead of the kernel named Linux (thus the name Debian GNU/Hurd). Some day, most applications will exist both in Debian GNU/Hurd and in Debian GNU/Linux.

Basic info

Official port site
GNU's GNU Hurd
Installation and testing:
- http://www.debian.org/ports/hurd/hurd-install
  - Debian "Sid" debian-installer images available http://people.debian.org/~sthibault/hurd-i386/installer/cdimage/.
  - This is the prefered method of install.
- Cross Hurd
- Pre-build image files (*.img.*) at http://people.debian.org/~sthibault/hurd-i386/

Goals for releasing in wheezy

buildd
- security
- DSA
proper dhcp support in installed system
- use ifup/ifdown instead of translators entry?
debian-ports packages need to be integrated in the main archive.
- binutils
  - 629866
  - Not critical, can live without
- cardmgr-gnumach
  - wifi, can live without

Be able to install at least the base from official mirror (should be almost done, missing grub/parted, dhcp)
Integrate DDE to get nowadays' network support.
Get Xorg + gnome/kde/xfce (xfce should work, kde is missing working dbus (due to local socket auth and bugs in select() cornercases)) + some webbrowser working (iceweasel 9 works, though not https).
Fix ext2fs uncleanness at reboot http://www.gnu.org/software/hurd/open_issues/sync_but_still_unclean_filesystem.html
Switch to plain sysv startup?
Enable console by default? (we now have proper kernel message relaying)
fix "su" to root discrepancy (PATH does not include sbin etc.)
Good archive coverage.
- We're at 70%, kfreebsd is at 88%. Although probably not reachable, we can probably do better with
  - ghc
  - mono
  - gnat
  - ruby1.9.1

ghc

Follow http://hackage.haskell.org/trac/ghc/wiki/Building/Porting

Make sure to use the same path in the host and in the target for the compilation.

For the triplet, use i386-unknown-gnu. Better cross-build from an i386 host.

Don't use perl boot: the package is already "booted".

After having run make in the host and transferred the files to the target, fixes are needed in files libraries/unix/dist-install/build/System/Posix/*.hs, basically all lines postfixed by {-# LINE 334 "librari...}

Notably: the offsets in ./libraries/unix/dist-install/build/System/Posix/Files.hs, use the following instead, and fix allocation from 96 to 128.

And then run make again, and copy ./libraries/unix/dist-install/build/System/Posix/*.hc (but only these files) to the target.

In <T>/mk/build.mk, append -lffi to ghc_stage2_v_EXTRA_CC_OPTS and -lffi -lncurses -ltermcap to utils/ghc-pkg_dist-install_v_EXTRA_CC_OPTS

Goals for later

IPv6 support in d-i (after it is settled for linux).
