[9fans] Canonical way to configure permanent remote cpu access

[Luke Evans <luke.evans@gmail.com>]

After many years of knowing about Plan 9 but apparently being too lazy to go find out about it, we now have it available on the Raspberry Pi (hurrah!).  The ease with which I can now install and learn about Plan 9 is now such that I have no excuse but to dive in :-)

Having got Plan 9 running on the Pi with the networking functioning and having also compiled the version of drawterm for Mac OS X cocoa, I'm now wishing to configure Plan 9 so that it permanently allows access from remote terminals for authenticated users.

I've found a way to achieve this temporarily from the console:
echo 'key proto=p9sk1 dom=plan9 user=glenda !password=MYPASS' >/mnt/factotum/ctl
aux/listen1 -t tcp!*!ncpu /bin/cpu -R &

This works great, but obviously does not survive a reboot of the system.  I'd like to know:
- Where's the right place to configure a permanent listener in the config/startup files?
- How should authentication be also permanently configured for any user that should be able to connect with drawterm?

Thanks in advance.
