I don't know for sure, but searching a bit, I've found 2 references to
syslinux :

You will need to have at least the following packages installed in
order to build iPXE:
[...]
- syslinux (for isolinux, needed only for building .iso images)
[...]

See page : https://ipxe.org/download?s[]=syslinux

And :

To be able to boot memtest, there are a couple requirements:

[...]
The memdisk kernel from the syslinux library
[...]

See page : https://ipxe.org/appnote/memtest?s[]=syslinux

So maybe add a comment somewhere explaining that those 2 things
won't work on any arch != x86_*

Maybe just add that to the commitmsg...

I don't know what iPXE uses syslinux for (CC Vincent); it appears to
build fine without it.  I made the dependency conditional on
architecture in d15972194aaef17fd1f7fd713d235c70794c9d4f, that way QEMU
should still work on aarch64.

(speaking of aarch64, Cuirass is slowly catching up now:
).

Thanks for the heads-up,
Marius

Hello Marius,

I just noticed that:

--8<---cut here---start->8---
./pre-inst-env guix build --system=aarch64-linux grub
/home/mathieu/guix/gnu/packages/bootloaders.scm:101:2: warning: package 
grub@2.06 does not support aarch64-linux
--8<---cut here---end--->8---

it seems to be because of the following dependency path:

--8<---cut here---start->8---
grub <- qemu-minimal <- ipxe-qemu <- ipxe <- syslinux
--8<---cut here---end--->8---

with syslinux that only supports x86_64-linux and i686-linux.

I'm not sure how to break that path. It looks like qemu-minimal is
required by grub for test purposes. Maybe we could restrict that
dependency and the tests to x86_64-linux and i686-linux?

WDYT?

Thanks,

Mathieu
