  Well, first we can use mkfs to build support for the ext* familly,
so that reduces the set of binaries to check. Otherwise XFS (and maybe
vfat) makes some sense to check, but I don't see the point for the
others which are either legacy unix/mac or formats with very specific
use cases, so yeah I would add an fsck.xfs check in configure.in too
