Just some braindumps. Do not read.

Introduction
------------
Shutting down the system.

When?
-----
- reboot
- halt
- power off
- further needed?

How / What?
------------
- Stop services in the correct order
   * reuse the service tree / needs / needed_by!
   * call off, if existent
   * if respawning, send SIGTERM?
      - not if off is existent?
   * give some variables to off?
      - $RESPAWN_PID: if respawning
- send SIGTERM to other apps?
   * or put that into special? special/post_svc_shutdown
- call special/{halt,poweroff,reboot}
- implement timely controlled shutdown:
   * cinit.shutdown forks (?) itself and waits, then sends a signal
     to cinit to initiate the shutdown process
- also implement halt
   * kill -TERM 1
- also implement reboot
   * kill -HUP 1
- also implement reboot
   * kill -USR1 1
