Title:
  grub-reboot changes boot default permanently on Lucid LTS

Status in “grub2” package in Ubuntu:
  New

Bug description:
  Binary package hint: grub-pc

  This is related to the following bug:
  https://bugs.launchpad.net/ubuntu/karmic/+source/grub2/+bug/497326

  Opening a new bug since the aforementioned bug is related to Karmic.
  Although it was marked as "fixed" over 16 months ago, this feature
  still appears to be broken in Lucid LTS.

  Ubuntu Release:  Ubuntu 10.04.2 LTS
  Architecture:  x86_64
  Package Version:  1.98-1ubuntu10

  Steps taken:
  - Edited /etc/boot/default and changed "GRUB_DEFAULT=0" to "GRUB_DEFAULT=saved"
  - Used grub-reboot so that grub would reboot into Windows on the next boot only
  - Rebooted from Ubuntu
  - Windows booted as expected
  - Rebooted from Windows

  Expected Results:
  - After rebooting from Windows, my grub default selection should be back to Ubuntu (or whatever it was before issuing grub-reboot) since grub-reboot is supposed to "set the default boot entry for GRUB, for the next boot only" as per the man page.

  Actual Results:
  - Windows remains selected by default at the bootloader screen and boots.  Note that this prevents users from being able to reboot into Windows and back when they are accessing their machines remotely.

  Additional Information:
  - The system I am experiencing this on is set up as follows:
  -   Ubuntu is installed on a Linux mdadm raid 1 mirror (/dev/sda1 and /dev/sdb1)
  -   Windows is installed on an Intel Raid 1 mirror (what would have been /dev/sdc and /dev/sdd are now /dev/mapper/isw_febcbhicb_Windows)
