(This was purly for testing sizes are rather arbatary)
Disk set-up
2M MacOS for booting
2M root slice 0
4M swap slice 1
8M usr  slice 2
8M Free A/UX slice 3
8M Free A/UX slice 4
8M Free A/UX slice 5
8M Free A/UX slice 6

Results:
disklabel returned that there were _8_ partions (I realize it only looks
for the first 8, but the map it returned had only 5 (4 not counting the
whole disk) partions in it.)

That was it.  No e,f or h for the Free A/UX slice [3-6] (or [3-5]).

Please ignore any variations in partion sizes.  The first test was run by
repartioning a SyQuest cartrige that I use for moving file in/out of MacBSD,
the second test run using a cartrige that is now set-up for doing these tests.


>From what I've seen so far, if you want more than 3 partions (root, swap, usr)
you have to create multiple usr partions and keep a mental note of
which one appears first on the disk as it is the one which will be used
for sd?g.  The others will then fill in sd?d,e,f,h  in the order they
appear on the disk.
