Clean up '#r' (it's still not great but it's better) and ifconfig

well, hey, it's free.

There's an issue with bind. If you
bind '#s' /srv
then /9/srv disappears. For now just
bind -b '#s' /srv

With this change, /9/dev, /9/srv, /9/proc, are there.

cs still doesn't quite work because the mount fails. That's
next.
