}  I'd rather have the dkwedge_gpt.c code set the partition type of the
}  fake label for the whole disk of the wedge to FS_SWAP when dkw.dkw_ptype
}  is DKW_PTYPE_SWAP.

     Should we be migrating away from the use of labels as an API
and have them as only a low level detail that gets buried and only
seen by utility apps?  We already have DIOCGSECTORSIZE and
DIOCGMEDIASIZE.  Maybe we need something like DIOCGPARTTYPE as a
generic way to get a partition type without needing to know anything
about the underlying partition scheme?
