This bug was fixed in the package grub2 - 2.02~beta2-22ubuntu1.2
---------------
grub2 (2.02~beta2-22ubuntu1.2) vivid-proposed; urgency=low
[ Mathieu Trudel-Lapierre ]
* debian/build-efi-images: look for grub.cfg in $cmdpath too in gcdx64.efi,
to simplify embedded scenarios: putting a grub.cfg snippet that loads the
right "real" grub.cfg can be useful. (LP: #1468111)

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).
