Package: grub-common
Version: 1.98+20100804-14+squeeze1
Severity: normal
On one squeeze machine grub-install fails since grub-probe fails. This
is puzzling since it works on a different squeeze machine with similar
setup.

I fetched grub from bzr (rev 3437) and it seems to correctly detect
the filesystem type:
data:~$ sudo /home/lindi/grub-install/sbin/grub-probe
"--device-map=/boot/grub/device.map" -t fs "--device" "/dev/md0"
[sudo] password for lindi:
ext2
I thought about backporting grub2 from wheezy but that seemed to build
depend on some gcc*multilib* stuff that I didn't have time to backport
at this point..
