If you think it's better having explicit _supported_fs lines for all
tests, I don't have any strong objections; I just wonder if it's
necessary.

Today "_supported_fs generic" is a no-op.  And I wonder if we could
just simply encoding an explicit check for FSTYP must equal the test
directory name if the directory name is not "generic" or "shared" in
the check script?

It looks great, thanks for sending it out.  I've sent a reviewed by
under separate cover.
