Bug#535525: grub-pc: Upgrade uses stale entry from devices.map

[Harald Braumann]

Package: grub-pc
Version: 1.96+20090603-2
Severity: normal

On upgrade, grub-pc asks on which devices I'd like to run grub-install.
The only option it displays, is /dev/hda. However, I only have /dev/sda.
It seems, that it only uses entries from devices.map, which might be 
outdated (as in my case). Also, there is no option to enter a device
manually.

grub-pc should either rescan the devices on upgrade or at least allow
the user to enter the device manually.
