Not being familiar with UBIFS, the explaination is rather brief and
doesn't explain anything to me. Can you document how where supposed
to treat a filesystem that doesn't exist on a block device for all
the tests that assume that the local fileystem is on a block device?
e.g. how do all the generic tests that use loopback devices work?
What about dm-flakey?

I'd like to avoid adding command line switches for random filesystem
types if at all possible. I'd much prefer that it be derived from
the current TEST_DEV if at all possible. Can you probe for UBIFS
similar to using blkid for local filesystems?

Needs a comment explaining what format we are searching for there?
