Bug#578201: grub-common: grub-probe reports incorrect fs type

[Aravind Gottipati]

My hypothesis that it was simply listing the fs type of the bootable
partition is incorrect.  I changed sda4 to be bootable, but its still
listing the fstype of sda1.  Also, I happen to have another
installation of debian thats not quite so up to date and grub-probe
seems to be working okay there.  Here is the output from the grub2
1.97+20091115-1, and following that is the output from the latest
grub2 1.98-1.


(this is the output from the older grub2)
