First off, if you want to add a comment to your mail but not to the commit message, you should add it below the first -- (under the commit message), before the diff, that way it doesn't end up in the commit message. With this applied, I cannot build an example qcow2 image using `guix system image -t qcow2 gnu/system/examples/bare-bones.tmpl`. It fails when installing GRUB onto the image. Sure enough, the install-grub-disk-image procedure seems to only support MBR. Could you also have a look at this? Best, -- Josselin Poiret
