Hey,

Strange, only 8 minutes for me. Does it include the time necessary to
fetch all substitutes? Are you using a SSD drive?

> $ qemu-system-x86_64 -m 1024 -bios $(guix build
> ovmf)/share/firmware/ovmf_x64.bin -hda /tmp/lightweight-desktop.img

It tries to mount the EFI file-system with UUID "1234-ABCD" and
fails. You can remove this one for the lightweight-desktop configuration
to obtain a bootable system.

Yes it is probably broken too. However, I would prefer not to introduce
bootloader specific stuff in (gnu system image).

I think the bootloaders should try to do their best with the DEVICE and
MOUNT-POINT arguments passed to bootloader-installer procedure. It
means, trying to install themselves using only MOUNT-POINT argument or
bailing out.

WDYT?

Thanks,

Mathieu
