[Bug 957262] Re: update-grub ran before update-initramfs resulting in a menu.lst without an initrd line

[Steve Langasek]

Nevermind about the other files; there's enough info in the term log to
figure this out.

So the grub update knows to take care of replacing the /etc/kernel-
img.conf line with a proper /etc/kernel hook, but then nothing ensures
this is called after the kernel upgrade.  The kernel postinst calls
update-grub too early, and it's not called again after upgrade.

We should probably just have grub call update-grub in the postinst when
the upgrade handling is triggered.

Title:
  update-grub ran before update-initramfs resulting in a menu.lst
  without an initrd line

Status in “update-manager” package in Ubuntu:
  Triaged

Bug description:
  I was performing a distribution upgrade from Lucid to Precise and was
  unable to boot after the upgrade.  Come to find out this was due to my
  menu.lst missing an intird line.  I had the following:

  title           Ubuntu precise (development branch), kernel 3.2.0-18-generic
  root            (hd0,0)
  kernel          /boot/vmlinuz-3.2.0-18-generic root=/dev/md0 ro quiet splash
  quiet

  I manually added in the initrd line and was able to boot.  I also
  reinstalled the linux-image package and the initrd line was created
  for the recovery boot option.  From what I could see in the apt-
  term.log file update-grub was run one time halfway through the upgrade
  and update-initramfs was run at the very end.  So I'm guessing because
  there wasn't an initrd available it wasn't added to menu.lst.
