Assuming /export is one file system on the server, put all
the exports in a single entry, something like: 
V4: /export -sec=sys -network 10.0.10 -mask 255.255.255.0
/export/usr/src /export/usr/obj /export/usr/ports /export/packages /export/library -maproot=root

OR you can just allow the clients to mount any location
   within the server file system using -alldirs like:
V4: /export -sec=sys -network 10.0.10 -mask 255.255.255.0
/export -alldirs -maproot=root

At least I think I got this correct;-) rick
