Whew! I just finished my upgrade to 1.6.1 this weekend.
Let's just say it was not a pleasant experience.
Anyway, most everything is working now, but I do have a couple of questions.
Following the install documentation very closely...
It says to "delete old binaries that were part of the previous 
version of NetBSD.
Ok... How do I determine what binaries are old? I guess I can go by 
date, but I'd
prefer a more definite way to find out.
ls -lt /usr/bin comes up with 3 files that are not 4/8/03.
