This posting (though old) says that FreeBSD disklabels are different from
NetBSD disklabels. Also back in 2011 NetBSD would overwrite a FreeBSD disklabel
on a FreeBSD MBR partition of type 165. FYI, NetBSD has been using a MBR
partition type of 169 for a long, long time.

My objection was to NetBSD and FreeBSD sharing a disklabel, not to two
instances of NetBSD sharing a disklabel.
