Yeah you are right. I'm getting the names reversed, but It is still true that FreeBSD divides a single partition table entry (slice in FreeBSD speak, partition in DOS/Linux), into sub-partitions. I think the naming is confusing. Surely, we should call the main partition a 'partition' and not a slice (same as everyone else), and then have some other name for the subdivisions that the disklabel editor creates.
