Fixed in 7d567af46b4e10ffafb1d0f76b524f5781460598.

This makes me think that ‘auto-partition’ should probably be called
‘auto-partition!’.

Hello,

I’ve tested the installer in a UEFI setup like this:

  qemu-img create -f qcow2 /tmp/t.img 2G
  $(guix system vm gnu/system/install.scm) -m 256 -net user \
      -hda /tmp/t.img \
      -bios $(guix build ovmf)/share/firmware/ovmf_x64.bin

Sometimes, the installer crashes with the attached backtrace: EBUSY
while mounting /mnt/boot/efi.  Strangely, if I go to a console at that
point and run ‘mount’, I see that /mnt/boot/efi is already mounted.

Thoughts?

Ludo’.
