Subject: [PATCH core-updates 0/6] Restore i586-gnu (GNU/Hurd) support
Date: Thu, 15 Aug 2024 18:54:59 +0200

Hello!

This patch series fixes Hurd support (i586-gnu) on ‘core-updates’,
as described <https://issues.guix.gnu.org/72315>.  It does so by
updating the ‘glibc-bootstrap’ tarball.

I built the new tarball from the third commit and dropped it
under gnu/packages/aux-files, which where the commit marked as
“DRAFT” picks it up.  Of course we’ll change that to a URL at
ftp.gnu.org/gnu/guix/bootstrap/i586-gnu once we agree on the
strategy.

For convenience, I uploaded the tarball here:

  https://people.bordeaux.inria.fr/lcourtes/tmp/glibc-stripped-2.39-i586-pc-gnu.tar.xz
  https://people.bordeaux.inria.fr/lcourtes/tmp/glibc-stripped-2.39-i586-pc-gnu.tar.xz.sig

  nix-sha256: 0x2x6w611k6v9qdabacawamw2475p04hm3s0q95xcg063wjq4ig2

I was able to build this successfully:

  ./pre-inst-env guix build \
    -e '(@@ (gnu packages commencement) glibc-final-with-bootstrap-bash)' \
    -s i586-gnu

I’ll try to build some more and see.

I’d like to push this to ‘core-updates’ soon since it’s probably the
last blocker before we can merge.

Thoughts?

Ludo’.

Subject: [PATCH core-updates 1/6] gnu: make-bootstrap: Fix cross-compilation of ‘%glibc-stripped’.
Date: Thu, 15 Aug 2024 18:58:29 +0200

Previously, ‘guix build bootstrap-tarballs --target=aarch64-linux-gnu’
or similar would construct a cross-libc where ‘%current-target-system’
is set.  This would lead to a failure in the
‘add-cross-binutils-to-PATH’ phase, which assumes that
‘%current-target-system’ is #f; indeed, ‘cross-libc’ already returns a
cross libc and so ‘%current-target-system’ must be set to #f.

* gnu/packages/make-bootstrap.scm (%glibc-stripped)[inputs]: Move libc to…
[native-inputs]: … here.

Previously the second ‘copy-recursively’ call would fail with EEXIST
since glibc <at> 2.39 already provides $includedir/include/mach.

* guix/build/make-bootstrap.scm (make-stripped-libc)[copy-mach-headers]:
Pass #:select? to ‘copy-recursively’ to exclude files already present
under INCDIR.

As of glibc 2.39, libdl.so and libutil.so are gone (they are part of
libc proper since 2.34), but empty .a files are provided for backward
compatibility with code using -ldl and -lutil.  Keep them.

‘glibc-stripped-2.39-i586-pc-gnu.tar.xz’ was built from x86_64-linux
from the previous commit with:

As mentioned on IRC, I've reconfigured my system to core-updates+this
patch series and it works for me.  I'm using a close variant of the
`devel-hurd.tmpl' from the hurd-team branch

    https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/system/examples/devel-hurd.tmpl?h=hurd-team

and removed the new imagemagick dependency

I’ve submitted a patch to remove it:

  https://issues.guix.gnu.org/72674

Regarding ‘hurd-team’, I admit I had forgotten about it.  What are the
important things we should bring over to ‘master’ or ‘core-updates’?

Thanks,
Ludo’.

Thanks, that's great.

I don't think so; most of it is not really finished.  Possibly

--8<---------------cut here---------------start------------->8---
d7562eae93 hurd: Support system init in /libexec/runsystem.
b9b5f1ee5f hurd-boot: Support system init: Create essential device nodes.
ddba840edd system: hurd: Add swap-services to hurd-default-essential-services.
--8<---------------cut here---------------end--------------->8---

that help booting the Hurd after installing it on real hardware from a
GNU/Linux Guix installation with `guix init ... /hurd'.  After `guix
init', you'll have to reconfigure the GNU/Linux system, adding
menu-entries from /hurd/boot/grub.cfg (at least, that's what I did using
some ugly regex parsing in config.scm).

But these are not so interesting, because they will support booting Hurd
only once.  Supporting a second boot is more tricky and only has these
even less finished patches

--8<---------------cut here---------------start------------->8---
fa003825ef DRAFT hurd-boot: Support second boot.
6b34e08e4d DRAFT hurd: Support second boot.
--8<---------------cut here---------------end--------------->8---

These only work if the filesystem is clean -- which most of the time is
not the case when you restart -- why would you restart if not for a
kernel crash.  That means you'll have to boot into GNU/Linux and fsck
/hurd.

I'm using

--8<---------------cut here---------------start------------->8---
59ae639ac6 DRAFT system: examples: Add devel-hurd.tmpl.
--8<---------------cut here---------------end--------------->8---

as a convenience to build a childhurd to develop in (as opposed to just
offloading to).

ISTM that I've been the only user of these and they're not all that
great.  So yeah.

Greetings,
Janneke

OK, thanks for explaining.  Let’s keep that in mind for our future Hurd
endeavors!
