Sort of, but not quite.   FreeBSD partitions divide up slices in to
nice neat separately mountable (if they are made in to file systems)
independantly addressable units.

I don't agree there.  Using slice & partition within slice is more
clear thatn partition and extended partition and may make newbees
heave a sigh of relief.

Yes, the socalled "dangerously dedicated" disk, sure.   On today's
large disks there is little reason to do it that way.
