Bug#498353: update-grub silently fails when device.map is not up to date

[Michal Čihař]

Package: grub
Version: 0.97-47
Severity: normal
File: /usr/sbin/update-grub

Hi

during some updates, I ended up with device.map not containing correct
mappings. In this situation update-grub silently fails without giving
any notice what is wrong. From tracing this script, I found it ends with
following commands:

+ test -e /boot/grub/device.map
+ GRUB_LEGACY_0_BASED_PARTITIONS=1 grub-probe --device-map=/boot/grub/device.map -t drive -d /dev/hda1
+ grub_root_device=

The problem was that I did not have mapping for hda in device.map (it
used to be hde in older kernel versions). I think update-grub should at
least tell that something is wrong and not silently fail.
