I gave this some more thought, and I think this could be less ad-hoc.  We're
treating XFS as if it were a "weird", unique thing just because it isn't biased
towards DOS-style boot like most filesystems are.

Instead, I've done something more generic, using our standard filesystem
probing engine which should be more reliable than a single memcmp.

I propose the attached patch.
