[Colin Watson]

Hello Mathieu, or anyone else affected,

Accepted grub2-signed into vivid-proposed. The package will build now
and be available at
https://launchpad.net/ubuntu/+source/grub2-signed/1.46.2 in a few hours,
and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

Bug description:
  TEST CASE:
  1. create ubuntu snappy image from 15.04/edge
  2. enable UEFI boot in the bios
  3. verify that it fails to boot and drops into a grub shell

  4. create ubuntu snappy image from 15.04/edge that got build with vivid-proposed
  5. boot and verify that uefi boot works this time.

  Snappy images have grub.cfg in $cmdpath/efi/boot, which then loads a
  better /efi/ubuntu/grub/grub.cfg which will look for the real file on
  the filesystem.

  Snappy personal image built as such currently fails to boot:
  sudo ubuntu-device-flash personal rolling --channel=edge --output image.img

  GRUB fails to find /boot/ which is the typical prefix, and fails to
  find /.disk/info which then really breaks $prefix.

  Workaround is to handle grub.cfg being in $cmdpath directly (in other
  words, in /efi/boot).
