The 9pi.img has both types of kernel in the dos partition. To boot
the pi as a cpu server instead of a terminal, change 'kernel=9pi' to
'kernel=9picpu' in config.txt, and copy cmdline-cpu.txt to cmdline.txt
But I think the query was about a simple way to connect to your own
plan 9 terminal with drawterm, without making it into a cpu server.

Actually that's not so. For example, a quick-and-dirty method posted
to 9fans by Luke Evans on 10 Dec 2012 (which applies to any Plan 9
terminal, not just the pi):
echo 'key proto=p9sk1 dom=plan9 user=glenda !password=MYPASS'
>/mnt/factotum/ctl
aux/listen -t tcp!*!ncpu /bin/cpu -R &
This will only allow the terminal owner to connect. For more general
cpu-like service on a terminal, I use this script (which requires some
prior setup with auth/changeuser to create the lib/keys file):
#!/bin/rc
auth/factotum -g 'user=miller dom=hamnavoe.com proto=p9sk1 !password?'
rfork ne
echo auth server password:
auth/keyfs -p $home/lib/keys
aux/listen1 -t tcp!*!ticket /bin/rc -c '/bin/auth/authsrv -d $net' &
service=cpu aux/listen1 tcp!*!17007 /bin/exportfs -a&
service=cpu aux/listen1 tcp!*!cpu /bin/cpu -O &
service=cpu aux/listen1 tcp!*!ncpu /bin/cpu -R &
Nowadays there's hardly any difference between cpu and terminal
kernels, and in fact I would advocate combining the two. Only a few
lines of kernel source code need to be changed to allow it to decide
at boot time whether to behave as a cpu server or terminal, depending
on the setting of service= in plan9.ini.
