Trond Myklebust bf11fbdb20 NFS: Add sysfs support for per-container identifier
In order to identify containers to the NFS client, we add a per-net
sysfs attribute that udev can fill with the appropriate identifier.
The identifier could be a unique hostname, but in most cases it
will probably be a persisted uuid.
