Bug#463391: update-grub: wrong root device

[Khaled Hosny]

Package: grub2
Version: 1.95+20080128-1
Severity: normal

update-grub sets my root partition to (hd1,0), however when grub boot it
seems to always consider the booting disk as (hd0). device.map files
maps my sda disk to hd1, this seems to be the cause of the problem. Now,
when booting grub fails to load the font file for gfxterm and the
background image, leaving me with a pinkish screen with no visible text
making it impossible to even boot manually. I've to use a livecd and
change hd1 to hd0 in order to boot again.
