Thanks, Skip. That would follow; this system is probably straight Fourth
Edition, certainly an old ISO...

I've never been 100% clear on the process for running updates; can I bring
myself up to current from where I'm at now and not have to reload or build
a fresh system? It's a VM and I can snapshot so I'm willing to give
anything a try ...

I'm looking at the directions in a (cached copy) of
http://plan9.bell-labs.com/wiki/plan9/Staying_up_to_date/index.html...

Is that still valid? What's the canonical procedure these days for updating
a system?

If that's roughly correct ... I'm running a single Plan 9 machine, combined
CPU and fileserver ... I run that command as the bootes user on the system
console?

Thanks!

Sean
