Here is my FS layout as reported by sfdisk

And this is the output from grub-probe

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.

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