If a start script link (e.g., /sbin/rc2.d/S730cron) in sequencer N has a stop action, the corresponding kill script should be placed in sequencer N-1 (e.g., /sbin/rc1.d/K270cron). Actions started in level N should be stopped in level N-1. This way, a system shutdown (e.g., transition from level 3 directly to level 0) will result in all subsystems being stopped.
