I have two scsi disks that I'd like to add to my running 1.5 system, but
I'm confused about how to use the disklabel program.  I have /, /usr,
and swap partitions on sd0 now; I'd like to mount /usr/pkg on sd1 and
/home on sd2, plus maybe a 128mb swap partition on each, in the event
that I add more memory someday.

 From looking at disklabels from other NetBSD installs, it seems that 'a'
is always used with the / partition, 'b' with swap, and 'g' with /usr.
Are these hard and fast rules, or just conventions?  To configure sd1 as
I described above, would I just replace the 'a' and 'b' lines in the
partitions section with the sizes and fs types I want?

Also, I see there is an "offset" of 1216 on partition a on each disk--do
I need to preserve that?
