Did you pass --image-size?  If not, it could be that the image size
estimate is slightly too small (see commit
a8ac4f081a9a679498ea42ccfe001f218bba3043).

The build log should contain something like:

  creating ~a image of ~,2f MiB...

where ~a is “raw” or “qcow2” depending on the “guix system” command you
used.

Could you check what happens if you pass a --image-size argument bigger
than that?

Thanks,
Ludo’.

I doubled it from ~10 GiB to ~20 GiB:

This example template uses EFI, which I'm not that familiar with. But I
suspect something about the bootloader or filesystems configuration is
wrong.

From 'gnu/system/examples/lightweight-desktop.tmpl':

  ;; Use the UEFI variant of GRUB with the EFI System
  ;; Partition on /dev/sda1.
  (bootloader (grub-configuration (grub grub-efi)
                                  (device "/dev/sda1")))

  ;; Assume the target root file system is labelled "my-root".
  (file-systems (cons* (file-system
                         (device "my-root")
                         (title 'label)
                         (mount-point "/")
                         (type "ext4"))
                       (file-system
                         ;; Specify partition here since FAT 
                         ;; labels are currently unsupported.
                         (device "/dev/sda1")
                         (mount-point "/boot/efi")
                         (type "vfat"))
                       %base-file-systems))

Actually, false alarm! After increasing the image size to 20 GiB, I
missed the messages about being out of space. Sorry for the noise!

Oh right, so the failure is probably unrelated to the image-size
estimate.

Marius, any ideas?  :-)

So the problem is that the estimate was too small, right?

It would be awesome if you could fiddle with the heuristics in there to
see what would work.  :-)

Thanks,

No, the problem was that I forgot about the estimator and tried to use
10 GiB, which was too small :)

I just tried the estimator and it worked fine.

Perfect.  :-)
