Actually, in OpenAFS, it's the CM that talks to the fileserver.  "fs" just 
makes system calls.

But yes, the theory is that the only interfaces that have to be provided to 
filesystem clients for things to work correctly are VL and RXAFS.  Only 
servers and administrative clients (including those usable directly by 
users, like "pts") should need to talk to services like PR or AFSVol or 
know which dbserver is coordinator.
