It's not an msdos partion AFAIK but dkctl(8) lists it like that:

# dkctl wd0 listwedges
/dev/rwd0: 6 wedges:
dk5: e8b85d79-899f-4cd6-964e-af3db098e992, 2048 blocks at 2048, type:

dk4: Swap, 9195520 blocks at 479201280, type: swap

For comparison, gpt(8) output:

Also AFAIK the primary bootstrap code is still installed on gpt3 (rdk2).
