Hello Marius,
> glib > gtk+ > + ipxe-qemu > libaio > libcacard ;smartcard support > attr libcap-ng ;VirtFS support 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
