john, eric, and yy, thanks!

9vx isn't working out very well for me so far. I'm trying to practice
everything in the documentation on the Plan 9 site, then I'll work on the
ideas that have been posted for me here. I was going to practice first in
9vx, because it's easier to switch back and forth between that and my other
windows, than between qemu and my other windows.

Adding a new user:

term% uname jim jim
> uname: '/bin/uname' file does not exist
>

That doesn't encourage me to try to use 9vx for what I'm doing right now.

I'll see if I can do any better in QEMU.
