Agreed.  It should be abstracted a bit -- "exportable via a file  
sharing service" -- and it should be a property of the mounted instance.

We can address this later -- it's not critical -- but it seemed like a  
good opportunity to bring it up given jmmv's statement that disabling  
the fh entry points are the only way to disable NFS exportability.
