When installing from the Guix install image, grub-install fails on my
x86_64 ASRock Beebox PC:

guix system: error: '/gnu/store/hsc3gsqbxkl64nx38sf2fgs2fxzbpr0i-grub-efi-2.04/sbin/grub-install --boot-directory /mnt/boot --bootloader-id=Guix --efi-directory /boot/efi' exited with status 1; output follows:

 Installing for x86_64-efi platform.
 /gnu/store/hsc3gsqbxkl64nx38sf2fgs2fxzbpr0i-grub-efi-2.04/sbin/grub-install: error: failed to get canonical path of `/boot/efi'.

I let the Guix installer (git master commit
fef2f08bc640f78cc0a86fc7be3eccbc07b5e98c) auto-partition my entire
disk without encryption.

“fdisk -l /dev/sda” shows:

Disk /dev/sda: 238.49 GiB, 256060514304 bytes, 500118192 sectors

Hello,

Pushed on master and cherry-picked on version-1.3.0 branch.

Thanks,

Mathieu
