Subject: [TUHS] Question about BSD disklabel history

Hi,
I've found myself wondering about partitions inside of BSD disk labels.
Specifically, when and where was the convention that "a" is root, "b" is
swap, etc?
I also understand the "c" partition to be the entire disk, unless it
isn't, at which point it's the entire slice (BIOS / MBR partition)
containing the BSD disklabel and "d" is the entire disk.
I also found something last night that indicated that OpenBSD uses disk
labels somewhat differently than FreeBSD.
Aside: This is one of the dangers of wondering how something curious
came to be and why it came to be when working on 10-15 year old FreeBSD
systems.
