Ok. That's definitely a start.

It's used by the firmware to boot the machine into MacOS. The "patches"=20
driver patches the firmware, and then one of these driver partitions=20
actually reads in the starting system file.

The main reason I wanted to map the names is that Apple tends to create=20
long-ish names, like on the order of 12 to 15 letters, while we tend to=20
stick to names from 3 to 6 letters. So anything which dumps a lot of=20
wedges & types will end up either chopping off part of the type or wasting=
=20
lots of space on wedges used for NetBSD (depending on how the "type"=20
column is formatted). Thus the desire for smaller names.

Thoughts?

Take care,

Bill
