Bug#479056: grub: destroys /boot/grub/device.map

[Aurelien Jarno]

Package: grub
Version: 0.97-33
Severity: critical
Justification: breaks the whole system

Starting with version 0.97-33, /usr/sbin/update-grub destroys
/boot/grub/device.map, and then outputs the following error message:

Searching for GRUB installation directory ... found: /boot/grub
grub-probe: error: Cannot find a GRUB drive for /dev/vda1.  Check your device.map.

Here is the contents of /boot/grub/device.map before it is destroyed:
(fd0)   /dev/fd0
(hd0)   /dev/vda

/dev/vda corresponds to the first virtio device.
