    Yes, although perhaps writing to tsec->kern_create_sid or similar, which
    then overrides tsec->create_sid if set. Also need
    /proc/pid/attr/kern_fscreate as a read only node.

    I wonder if we also need 'relabelto' and 'relabelfrom' permissions, to
    control which labels are being used.
