Going from 1.6.1 to 2.0

	My DEC5000/25 is currently running 1.6.1 in a 512MB HD.  I 
have a 2GB HD I have been meaning to replace the HD in the dec box 
with. As netbsd 2.0 is out there, I thought on doing both at the same 
time.  After reading through the install docs, it seems I would be 
better off doing a full install and then moun the old HD so I can 
suck the stuff out of it.  Other than /etc (since the machine is used 
as my home's dns and dhcp server) and my home directory (since I kept 
a copy of the programs I added), are there any other files I should 
save?
