This is not a reliable test.  _Any_ external file system volume (CD-ROMs, 
NFS "volumes", etc.) will have a non-zero FSID.  Additionally, I don't 
believe that AppleShare can use a fixed non-zero FSID for its own volumes; 
it has to derive a value for the FSID based on any other non-zero FSIDs in 
use the first time an AppleShare volume is mounted.
