[TUHS] Question about BSD disklabel history

[Grant Taylor via TUHS]

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.
