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.
