[Bug 1510120] Re: UEFI deployment broken in MAAS 1.9

[Blake Rouse]

The issue here is that the grubnetx64.efi.signed file in grub-efi-
amd64-signed package in trusty does not contain the LVM module. So if
you deploy with the flat storage layout every thing works, if you deploy
with LVM it will fail to boot from the local disk.

I built a custom grub that includes the LVM module and the system was
able to boot correctly.

The issue is that the grubnetx64.efi.signed is not being built with
lvm.ko.

  UEFI deployment broken in MAAS 1.9

Bug description:
  UEFI-mode deployment seems to be broken in MAAS 1.9. Enlistment and
  commissioning work fine, as does most of deployment; however, there
  seems to be a problem with the GRUB configuration. Instead of the
  normal boot at the end of deployment, I get a GRUB menu with one
  option. Selecting that fails and, after a prompt to press a key,
  brings up the same menu. The GRUB on the hard disk seems to work,
  though; I'm able to boot to it via a boot to rEFInd on a USB drive and
  boot the system. Thus, it seems to be the GRUB being sent via PXE from
  the MAAS server that's unable to redirect to GRUB on the hard disk (or
  use the disk-based GRUB files).

  Here's the version information:

  reconfigured my two UEFI-based nodes to boot in BIOS/CSM/legacy mode
  to work around this issue for the time being.
