Well, I apologize that we're getting off the whole NetBSD topic, but at
least we're staying with the Mac part...  Clean install means making a new
system folder, and leaving the old one but "unblessing" it so that it no
longer acts as a system folder.  AFAIK, no version of the MacOS does a
clean install by default.
	I do agree that a clean install is much more stable, and it is
probably the way to go for a NetBSD box.  Make sure that you don't do a
minimum install, since NetBSD doesn't like that (I don't know why not,
it's not my department...).
	As far as speed increases go, each separate version of the OS
(7.0, 7.1, 7.5.x, 7.6, 8) should increase in speed slightly, and
reliability somewhat, but will usually (not always) also increase in disk
and RAM footprint, and will support fewer machines.  Personally, I'm
running 7.1 on my IIci, since I'm in MacOS for about 30 seconds every
month or so...  I'm most concerned with disk space, and I don't really
care about anything else.
	Personally, if I had an 840AV, I'd probably put 7.6.1 on it, but I
haven't actually tried this, so I can't guarantee that this is a good
	Good luck with the upgrade and the NetBSD install!
