Something appears to have broken with grub, such that the current version in
rawhide is no longer able to install a boot loader using grub-install.

grub-1

With grub-0.95-15 this is what happens:

[root@typhoon ~]# grub-install /dev/sdc
No suitable drive was found in the generated device map,
reverting to backed up copy.
mv: cannot stat `/boot/grub/device.map.backup': No such file or directory
[root@typhoon ~]#


With grub-0.95-13 installation looks like this:

[root@typhoon reuben]# grub-install /dev/sdc
Installation finished. No error reported.
This is the contents of the device map /boot/grub/device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script `grub-install'.
