CIFS doesn't support symlinks (they just appear as the referenced file), so I've had applications that scan the filesystem recurse indefinitely due to symlinked directories on a CIFS share appearing as hard-linked directories on the client.  This doesn't happen when the filesystem is accessed via NFS.
