finit(8) 0.3.3 turn the lights on ================================================================================ Name -------------------------------------------------------------------------------- fiss - a UNIX process no 1 Synopsis -------------------------------------------------------------------------------- Controlling -------------------------------------------------------------------------------- If finit is invoked by any other user than root, it failes. Description -------------------------------------------------------------------------------- fiss must be run as Unix process no 1 if invoked without arguments and handles the boot process in user-land. This happens in three stages: Stage 1 -------------------------------------------------------------------------------- fiss runs /etc/fiss/start and waits for it to terminate. The system's one time tasks are done here. /etc/fiss/start has full control of /dev/console to be able to start an emergency shell if the one time initialization tasks fail. If /etc/fiss/start crashes, finit will skip stage 2 and enter stage 3. Stage 2 -------------------------------------------------------------------------------- fiss starts all services in /etc/fiss/service.d which should not return until system shutdown; if it crashes, it will be restarted. Stage 3 -------------------------------------------------------------------------------- If fiss is told to shutdown the system, it terminates stage 2 if it is running, and runs /etc/fiss/stop. The systems tasks to shutdown and possibly halt or reboot the system are done here. If stage 3 returns, finit checks if the file Signals -------------------------------------------------------------------------------- finit only accepts signals in stage 2. If finit receives a CONT signal and the file finit is told to shutdown the system. if finit receives an INT signal, finit restarts the system.
