The Lustre client mount device is NOT a block device. There is no code 
(like for an NFS client mount) that handles this exception.

There is support for Lustre server (MDS, OSS) mounts because in that 
case the device is a block device. The trouble stems from the fact that 
the fileysstem type "lustre" is overloaded for both server side and 
client side mount purposes.
