Bug#423104: Another similar problem

[Yann Dirson]

Now the new grub fails to install with:

|Setting up grub-pc (1.95+20070520-1) ...
|Updating /boot/grub/grub.cfg ...
|cannot find a GRUB drive for /dev/dm-8.
|dpkg: error processing grub-pc (--configure):
| subprocess post-installation script returned error exit status 1

Not sure why it wants to do with what appears to be my /usr partition:

brw-r----- 1 root disk 254,  8 Apr 24 00:47 /dev/evms/usr
brw-rw---- 1 root disk 254,  8 Apr 24 00:47 /dev/dm-8

Any clue ?
