This is a minor update to change the requirements text for operating systems that don't
support the pNFS block layout.  Instead of the "SHOULD" requirement to check the
GPT for all such systems (that was in the -01 version), the new draft says:

   Data stored on pNFS block layout storage devices can be better 
   protected by incorporating checks for this GUID into other hosts and 
   systems that do not support pNFS block layouts.  If pNFS block 
   storage devices are presented to such hosts or systems by mistake, 
   the check for presence of this GUID can be used to prevent writes 
   that could otherwise corrupt stored pNFS data.

Thanks,
--David

   Parallel NFS (pNFS) extends Network File System version 4 (NFSv4) to
   enable direct client access to file data on storage, bypassing the
   NFSv4 server.  This can increase both performance and parallelism,
   but requires additional client functionality, some of which depends
   upon the type of storage used.  The pNFS specification for block
   storage (RFC 5663) describes how clients can identify the volumes
   used for pNFS, but this mechanism requires communication with the
   NFSv4 server.  This document adds a mechanism to RFC 5663 that
   enables identification of block storage devices used by pNFS file
   systems without communicating with the server.  This enables clients
   to control access to pNFS block devices when the client initially
   boots, as opposed to waiting until the client can communicate with
   the NFSv4 server.
