[Bug 1245154] Re: grub-efi grub.cfg generated with incorrect commands, linux and initrd, instead of linuxefi and initrdefi

[Colin Watson]

The secure boot patches in Ubuntu *do* modify linux and initrd to call
linuxefi and initrdefi as necessary.  It is absolutely incorrect to
change grub.cfg to use linuxefi and initrdefi.

Title:
  grub-efi grub.cfg generated with incorrect commands, linux and initrd,
  instead of linuxefi and initrdefi

Status in “grub2” package in Ubuntu:
  New

Bug description:
  grub.cfg is generated with incorrect commands, linux and initrd,
  instead of linuxefi and initrdefi. This affects both the install .iso
  for the latest Ubuntu 13.10 and the installed system of the latest
  Ubuntu 13.10.

  Simple Workaround:

  You can hand-edit the commands in grub to boot the target system. Once
  inside, then you can edit /boot/grub/grub.cfg to change all linux and
  initrd commands to linuxefi and initrdefi, respectively. This will
  have to be updated each time the grub.cfg file is regenerated, i.e.,
  whenever new kernels are updated.

  Configuration Patch (Proposed Fix, Untested):

  Then to ensure grub.cfg is regenerated correctly, edit
  /etc/grub.d/10_linux so that

  line 166 says linuxefi instead of linux

  and

  line 182 says initrdefi instead of initrd

  But line 182 probably needs to be updated to include encapsulating
  code that tests for efi just like on lines 164-172 via an:

  if test -d /sys/firmware/efi && test -e "${linux}.efi.signed"; then
  (...use initrdefi) else (...use initrd) ... fi.

  Thanks!
