sda4 is not ufs1, I do have a ufs partition on this disk (sda1), but
sda4 is not it. This is causing grub-mkconfig to generate bogus
entries in the 10_linux (os-prober?) script and screwing up my
grub.cfg file.

It appears that grub-probe is returning the fs type of whatever
partition is marked as bootable, and not the fs type of the partition
queried.

root@dogmatrix:/etc/grub.d# /usr/sbin/grub-probe --device /dev/sda1 --target=fs
ufs1
root@dogmatrix:/etc/grub.d# /usr/sbin/grub-probe --device /dev/sda4 --target=fs
ufs1
root@dogmatrix:/etc/grub.d# /usr/sbin/grub-probe --device /dev/sda2 --target=fs
ufs1

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.
