My 5000/25 has 1.5.2.  Until my Solaris box had a HD crash, I 
really had not been using the Dec often.  However, it may be called 
to do some of the job the SS20 did.  But, beofre that, I would like 
to upgrade netbsd.  What is the sanest/easiet way to do it:  full 
install (as I really do not have that much done to it) or upgrade? 
If the upgrade, how to do it?  I have read the docs and am still 
rather confused.
