I don't think you can shoot your foot off.  The Domain registry tools
will not let you remove a required account.  
/etc/server (essentially) does a setuid, setgid, and setoid to run as the 
user.server.none SID, so I don't think that you need an account set up in 
order for it to work.

True.


I wonder if some/all of these accounts are from the transition period, or
were required at sr9.7....
