!   restartinit, restartinit0 and restartinitreboot
  
!     These three boolean elements control what action is taken when the
!     program specified by the 'initname' element exits.
  
!     The default values are:
! 
!         restartinit:       true
!         restartinit0:      false
!         restartinitreboot: false
! 
!     If 'restartinit' is set to false then the init process will never be
!     restarted and the zone will shut down once init exits. In this case, the
!     other restartinit elements are ignored.
! 
!     When 'restartinit0' is set, init will only be restarted if it exited with
!     an exit status of 0, otherwise the zone will shut down.
! 
!     If 'restartinitreboot' is set to true then whenever init should be
!     restarted, based on the other restartinit elements, the zone will instead
!     be rebooted.
! 
!     These have no attributes.
