Bug#697592: grub-update does not update device.map when hdd was replaced

[Claudio Kuenzler]

Package: grub
Version: 0.97-64
Severity: important
Tags: squeeze

The command "update-grub" should update /boot/grub/device.map if there was a change of hdd (e.g. replacement).
I had two servers where I recently replaced a defect hdd but even after running update-grub the device.map was not updated with the new path to the new disk.
This has caused a big problem during the last boot cycle as the machine could not boot anymore (was stuck at grub boot screen). 

IMO update-grub should check for validity of /boot/grub/device.map and replace a non-existant entry with the new hdd name.

A workaround is to remove /boot/grub/device.map and then run update-grub. The file will then be created with the correct hdd paths/names.
