grub-reboot should warn that default=saved is required

[Daniel Hahler]

Binary package hint: grub2

It appears that grub-reboot only works with default=saved, and therefore using it should warn the user if default is not set to "saved".

[Reinhard Tartler (siretart)]

This is indeed very unobvious.
How about:
 a) setting GRUB_DEFAULT to 'saved' by default (current natty installer doesn't)
 b) documenting this in grub-reboot(8)

[Launchpad Janitor (janitor)]

This bug was fixed in the package grub2 - 2.02~beta2-5

---------------
grub2 (2.02~beta2-5) experimental; urgency=medium

  * Add a number of EFI debugging commands to the signed image (lsefi,
    lsefimmap, lsefisystab, lssal).
  * Add gfxterm_background to the signed image so that background_image
    works in UEFI Secure Boot mode. Thanks to syscon-hh for the report.

Pretty sure this bug was inadvertently fixed.
None of these mention GRUB_DEFAULT at all:
  grub-reboot --help
  man grub-reboot
  info grub-reboot

[Scott Moser (smoser)]

well, i'll mark this back to fix-released.
https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1102925 has more info, and there is now information in info.
