There's probably no BSD disklabel on the mac68k disk at all. The
disklabel is faked, on the mac, from the Apple partition map. You could
try to write one, with "disklabel -r -R protolabel", using the output
from "disklabel" on the mac as the protolabel, and hope it doesn't trash
the Apple Partition map.

Does "disklabel -N -R protolabel" do that? If it doesn't, I think it
would be good if it did.
