Title:
  'loadfont unicode' fails in SB-signed EFI image; image and grub-
  install don't agree on path

Status in “grub2” package in Ubuntu:
  Fix Released
Status in “grub2” source package in Quantal:
  Fix Released

Bug description:
  The stock grub config does the following:

  if [ x$feature_default_font_path = xy ] ; then
     font=unicode
  else
    [...]
  fi
  if loadfont $font ; then
    [...]

  'loadfont unicode' fails in the SecureBoot EFI image with this error:
    error: file `/EFI/ubuntu/fonts/unicode.pf2' not found.

  From what I can tell, this is because grubx64.efi (from debian/rules)
  is built with -p /EFI/ubuntu, but grub-install copies the font to
  /boot/grub/fonts (which of course is not on the EFI system partition).
  In the non-SB image generated by grub-install, the prefix is set to
  /boot/grub, so there's no problem; but for the SB image, we don't know
  where /boot/grub will be.  Either grub.cfg has to be changed to search
  for such files in the SB case, or the fonts (and locales) need to be
  installed to /efi/ubuntu and not just to /boot/grub.
