Scott, AIUI this is a case where a given partition has both LUKS and RAID
signatures, and the LUKS signature is given precedence.  I believe this is a
specific corner case that we overlooked in the previous patch, and that RAID
signatures need to be given precedence over LUKS.

For the general case of filesystem types, it still holds that LUKS should
take precedence; this particular bug only arises because both RAID and LUKS
are treated specially in blkid (on the grounds that both require manual
configuration to be activated) but the order of precedence is wrong.
