This has not made it into my Woof alpha7. Please see Jesse's forum post and test it:
If it tests out okay then it will be in Woof beta1.

I tested the new guess_fstype. It properly identifies the partition as ext4 now. I replaced the original guess_fstype with the new one, but pmount still will not mount the ext4 partition.
