 log into and use be controlled by a password you're typing everywhere.
 
 So you get a root instance, and only type the root instance password

 You can also make things in Moira or AFS owned by your root instance,
 if you don't want your null instance to be able to mess with mailing
 lists or lockers. For Moira, make them owned by
-`KERBEROS:yourname/root@ATHENA.MIT.EDU`. For AFS, ask accounts or afsreq to get
-you a 'pts id', basically an account with the AFS servers, and then
-you can give bits to yourname.root and start blanching your root
-instance onto AFS groups.

 To use another instance, just specify it to the kinit command, e.g.,
 `kinit joeuser/root`.
