* bug#55806: gnu/system/install.scm includes (service uvesafb-service-type) in %installation-services on all architectures

Reproducer:
guix system image -t iso9660 gnu/system/install.scm
This command fails on aarch64 host. It doesn’t if I manually remove uvesafb-service-type from the list. It is impossible(and not needed) to run uvesafb on non-x86 machines at the moment, so I think it should be included only in x86_64 (and probably 32bit x86 as well) builds.

I can definitely write a patch for that, it won't be worse that what we
have right now.  I wonder how we could handle the case when there's no
KMS for a particular hardware combination (if that's possible), since
kmscon requires that.  FTR, we require kmscon to be able to display
non-latin fonts such as CJK or arabic in the installer.

Now that I think about it, if we have a hard requirement on KMS, we
could just use a lightweight wayland compositor like cage to display the
installer, which would likely simplify the process since we'd have more
"usual" tools at our disposal.

Best,

* gnu/system/install.scm (%installation-services): Refactor into a
procedure, so that it can capture the system it's installing for.
Conditionally add uvesafb-service-type based on whether v86d is
supported by the target architecture.
(installation-os)[services]: Use the %installation-service procedure.

Thank you so much Josselin.  I didn't know how to do this.
At the time building for ARM was no priority.

I had to remove the (guix (current-guix)) but now `guix system image
-t iso9660 gnu/system/install.scm` builds on a rock64 aarch64 machine,
but it is still building and I could not yet test in qemu.  I have not
tried the embedded-installation image.

(I also had to disable tests on guile-fibers, but it is unrelated to
the bug and may be needed only on rock64, which has other unrelated
hangups when much RAM is used.)

I don't commit much except translations, but guess I should remove the
not working %host-type shenanigans in uvesafb-service-type, add your
copyright line and push.  I will do so when there are no other
comments.

Regards,
Florian

Silly me, I really should move some of my WIP patches to other branches
to avoid these issues :(

Feel free to commit with the changes you mentioned, and thanks for the
tests (I only checked minimally with cross-compilation since I don't
have any aarch64 machines)!

Best,

Pushed as 0aa43117907581779cf3f343c6175d98369b7e07.

Closing, even though I didn’t manage to boot it on QEMU.

Ideally Guix System would run as seemlessly as the Ubuntu ARM cdimages
work on Macs, but I can’t test and it is a different issue.

Regards,
Florian
