David's statement is incorrect. They like the same labels
for all practical purposes. The problem at hand here is
that fsck(8) & newfs(8) ask of GEOM_BSD what the partition
type is. This means 2 things:
1.  Any platform that doesn't use the BSD disklabel by
     default needs to have a proper /etc/fstab and is not
     behaving the same as i386.
2.  Switching to GPT as the default partitioning scheme
     yields the same problem.

As I said in an email to arch@, it's good to query the
partition type to determine what to do when more specific
information is missing (running fsck(8) vs fsck_ffs(8)).
But it wasn't something that was there at the switchover
point.
