INSTALL
*** service=cpu in plan9.ini
1. set service=cpu in plan9.ini, ensure that there is a newline at the end
2. startup scripts:
cd cirno;
cp cpustart /cfg/$sysname/cpustart # ensure diskparts is called
cp fsconfig /cfg/$sysname/fsconfig
cp namespace /cfg/$sysname/namespace
cp profile $home/lib/profile
cp on.rc $home/bin/rc/on.rc # script to stop fossil + vent
3. edit /lib/ndb/local, add auth and authdom
   7.4.1 - Configuring an auth server
   add the below line
    ipnet=9front ip=192.168.0.0 ipmask=255.255.255.0 auth=cirno authdom=9front
3. configure nvram (use the same password here and in #4 below)
   7.3.2 - Configuring nvram
   auth/wrkey
4. add users
   7.4.2 - Adding users
   auth/keyfs
   auth/changeuser glenda
