    NFS: Add nfs4_unique_id boot parameter · 6f2ea7f2

    An optional boot parameter is introduced to allow client
    administrators to specify a string that the Linux NFS client can
    insert into its nfs_client_id4 id string, to make it both more
    globally unique, and to ensure that it doesn't change even if the
    client's nodename changes.
    
    If this boot parameter is not specified, the client's nodename is
    used, as before.
    
    Client installation procedures can create a unique string (typically,
    a UUID) which remains unchanged during the lifetime of that client
    instance.  This works just like creating a UUID for the label of the
    system's root and boot volumes.
