 FreeBSD's ext2fs doesn't handle extended attributes at all, except it is
 supposed to disallow mounting of file systems that use them (even for
 read-only mounts).
 
 The set of features known to FreeBSD's ext2fs is smaller than the set known
 Linux's ext2fs and is much smaller than the set of features supported.  The
 former was last up to date 6-7 years ago.  All features newer than this are
 supposed to prevent mounting.  ext2fs in Linux also does a better job of
 downgrading attributes so that mounting is possible.
