GNU/Hurd on real hardware

GNU/Hurd on real hardware

[Gabriel Wicki]

Hi y'all

Following the inspiration given in the recent blog post I dug out an old
ThinkPad T410 and tried my best.

Unfortunately the installer created from a recent checkout crashes with
a kernel panic.  Does anybody know what commit a working installer for
GNU/Hurd can be built with?

TIA,
g

That's great, thanks for trying!

As you may have seen in <https://lists.gnu.org/archive/html/guix-devel/2024-11/msg00259.html>,
I succeeded in building a 32bit installer from commit

--8<---------------cut here---------------start------------->8---
commit cd26d76fedb7ab13ad91bd5dcfce119892b8e62e
news: Add entry for the Guix survey.
--8<---------------cut here---------------end--------------->8---

using this extra patch

because with the default 6.x kernel, my X60 panics.  AFAIK there is
nothing special about that commit, it's just a more recent one than
I had been using for earlier images.

Anyway, building it by doing

--8<---------------cut here---------------start------------->8---
make && ./pre-inst-env guix system image --image-type=iso9660 --system=i686-linux gnu/system/install.scm 
=>

--8<---------------cut here---------------end--------------->8---

I was hoping this would fix it for everyone, however, Tanguy reported
that installer also panics for them.  So yeah, YMMV.

Greetings and good luck!

`origin/keyring` exist and its last commit is f8868dd56bff0f282329a33abb62262b2fc584b6

The "good" news is that it doesn’t seem to be a bug related to the Hurd! 😁

Ow terrible, you got hit by #57229.  Luckily, I found a workaround (See
<https://issues.guix.gnu.org/57229#3>): run: guix pull --url=$PWD That
authenticates the branch.

Weird!  Hum, I think it’s mixing two things (local checkout and
~/.cache/guix/checkout/pj…) for one authentication cache, so maybe
that’s why an error pops up.  I suggest to populate the authenticate
cache first (guix time-machine) and then play with Hurd. ;-)

--8<---------------cut here---------------start------------->8---
$ guix time-machine -q --commit=cd26d76fedb7ab13ad91bd5dcfce119892b8e62e -- describe
$ git checkout -b test_hurd cd26d76fedb7ab13ad91bd5dcfce119892b8e62e
$ make -j8
$ echo cross fingers…
$ ./pre-inst-env guix system image --image-type=iso9660 --system=i686-linux gnu/system/install.scm
$ echo …yeah!
--8<---------------cut here---------------end--------------->8---

This works for me… Aside I have not tweak Linux kernel.

Thanks for the workaround! I’ll try this as soon as I can.
For the time being, my computer is busy building ARM stuff, as I have
successfully turned it into a "build farm" to offload my Olinuxino build jobs to! 😎

Thanks for having taken the time(-machine) to try and build it!
I’ll also try this workaround… as soon as my build farm is at rest!
