Eric and Anthony, thank you.

I'm stepping through the Plan 9 documentation at
http://plan9.bell-labs.com/wiki/plan9/documentation/index.html. As you
noticed, Anthony, I missed a step in adding a new user:

con -l /srv/fscons
>

That didn't work in 9vx either, I imagine for the reasons you explained. I'm
still way over my head here.

For now I'll use QEMU to step through the Plan 9 documentation, and later I
might use 9vx for other learning purposes. Now that I've learned to change
the display dimensions, and use ctrl-alt, it's easy to switch between QEMU
and my other windows. I've already created a new user.

I won't push my luck tonight. I'll wait until tomorrow to try network
configuration.
