The extfs uses type 83, but I wonder if it makes any difference at all.
I once accidently set up a partition as type 81, and then did a mkefs on it,
and all appeared to work ok!
The only thing that cares at all about the partition types (in Linux)
is fdisk, and it only uses that to print out the partition type name.
Neither mkfs nor mkefs make any use of the partition type.
A possible problem is DR-DOS, however, which apparently ignores the
high bit in partition ids, so it sometimes confuses type 80 with type
0, type 81 with type 1, etc. This has been reported by several
people, but I've never seen the problem myself.
Really, I think we should shift down to a better number - the whole
30-40 range is unused, according to all the documents I've seen, so I
would recommend something like:
30: swap (Linux)
31: minix (Linux)
32: extended (Linux)
33: extended two (Linux)
34: xiafs (Linux)
..: whatever (Linux)
But hey, it just depends on current usage, really, because none of the
Linux utilities care.
