Gotcha.

Yeah, I think prep doesn't want to set up "c" as the NetBSD part, and
"d" as the entire disk. I took your advice below on setting this up.

Well, actually take a look at the "a" part again. It starts from 0.
That's no good. I re-did it to start after the first fdisk partition,
and of course that will require me to either restore "a" or reinstall.
I did a dump of "a" over NFS but I had some weird NFS problems (does
prep act strange as an NFS client?). We'll see. I don't have too much
time invested so re-installing wouldn't be the end of the world,
either.

Seems kind of weird that disklabel behaves like this.

Once again, thanks for your help. I'm hoping to make a post to this
list with the stuff I've learned. Seems that it's mostly the same as
the older releases though.
