I've used CVS enough to know that the whole system can be very
confusing to non-idiots. Keeping track of where you are, and
what you're doing is non-trivial.

Ok, so the important thing it to know the changes a file has been
through, rather than where it was. That's reasonable in a project
like NetBSD, drivers, for example, can go from arch/x back up to
something generic as they're cleaned up.

That's fine too. Date based might be nice for certain branches of
-current from time to time, but certainly is a minor thing to give

Since the methods you use are not documented anywhere that I know
of, I really can't come to a conclusion about how good your "careful"
methods are - without a lot of trial and error checkouts and examination
by hand. So tell me, how are normal mortals de-moronified when they
are given CVS access?

Suggesting that listening to someone may be 'idiotic' rather subtracts
from the credibility of your message.
It is much more worthwhile to explain the process _thoroughly, once_
and then point people who ask back to that documentation.
For an Open-Source project, it does sometimes seem that there are
a lot of methods in use that don't get treated with the same level
of open-ness as the code is.

I didn't say that. The repository being more 'completely' available
means that people may make more thorough use of it now. Knowing
whether I can use anonCVS and check out a copy of the 1.2 tree
complete and intact is important.
