: 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

: 2.  Switching to GPT as the default partitioning scheme
:      yields the same problem.

: As I said in an email to arch_at_, 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.

But my problems are with a platform that has BSD labels, and not GPT
labels, with a proper BSD label on the device.  mount works properly
without extra args, but fsck doesn't and this is a new behavior
introduced recently...  I know this because I'd been messing with this
disk in an enclosure several weeks ago and also playing with cardbus
fixes, some of which hung my machine (which means that the disk wasn't
cleanly unmounted, so I was doing a lot of fsck).

% disklabel da0s1
# /dev/da0s1:
8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
  a: 976767986       16    4.2BSD     2048 16384 28520 
  c: 976768002        0    unused        0     0         # "raw" part, don't edit

I'll have to go read things on arch_at_.
