What's the urgency? You've got four slices without using extended one which gives 32 partitions easily. If you need more then that on x86, your time would probalby be better spent figuring out the issues involved in booting from a GPT partition and cleaning up the code in sbin/gpt on FreeBSD. That would give you nearly 16K partitions per disk which ought to be good enough for almost anyone. We're going to have to go that way soon anyway since >2TB disks don't really work with MBR partitions. -- Brooks -- Any statement of the form "X is the one, true Y" is FALSE.
