Title:
  grub-reboot does not select kernel

Status in “grub2” package in Ubuntu:
  In Progress

Bug description:
  [Ubuntu 12.04.1 LTS server x86_64]

  If I do

  [code]
  # vi /etc/default/grub
  GRUB_DEFAULT="2>20"
  # update-grub
  [/code]

  then I can select the default kernel to be used on next reboot.

  However I believe it should be possible to do this in a one-shot way
  with grub-reboot, and this doesn't work.

  [code]
  # grub-reboot "2>20"
  # cat /boot/grub/grubenv
  # GRUB Environment Block
  saved_entry=2>20
  prev_saved_entry=0
  ################################
  ...
  # reboot
  [/code]

  At reboot I just get the default kernel selected.

  It doesn't appear to be anything to do with submenus[*] because "grub-
  reboot 1" doesn't even select the recovery option from the main menu.
