 This behaviour can be controlled with 'dkctl keeplabel' and,
 by default, is only enabled for the vnd driver.
 
 
                 sc = vnd_spawn(unit);
                 if (sc == NULL)
                         return ENOMEM;
  
                 /* compatibility, keep disklabel after close */
                 sc->sc_flags = VNF_KLABEL;
 
 
 I have no idea where that compatibility is required or wanted.
