Hello Janneke!
I had a look to (gnu system hurd), this is really nice! I think we could
try an explosive mixture of our two branches :)
More seriously, we could do something like:
--8<---------------cut here---------------start------------->8---
(define hurd-disk-image
(image
(format 'disk-image)
(partitions
(list
(partition
(size 'guess)
(label "Guix_image")
(file-system "ext2")
(flags '(boot))
(initializer (gexp initialize-hurd-root-partition)))))))
--8<---------------cut here---------------end--------------->8---
then we could have some mapping in guix/scripts/system.scm to
associate:
* x86_64-linux -> efi-disk-image
* i586-pc-gnu -> hurd-disk-image
and one could get a hurd disk-image by typing:
--8<---------------cut here---------------start------------->8---
guix system disk-image --target=i586-pc-gnu my-hurd-os.scm
--8<---------------cut here---------------end--------------->8---
One problem that can arise is the installation of grub. Currently
wip-disk-image does not support legacy Grub (MBR based)
installation.
This is because running grub-install needs root permissions, to mess with
/dev/something in order to write the MBR I guess.
We could also create a Hurd ISO if grub-mkrescue (that is used to make
the ISO bootable), supports the Hurd.
Adding Ludo that might have some insight here.
Thanks,
Mathieu
