NAME

       runit - a UNIX process no 1

SYNOPSIS

       runit

DESCRIPTION

       runit  must  be  run  as  Unix  process no 1.  It performs the system’s
       booting, running, and shutdown in three stages:

STAGE 1

       runit runs /etc/runit/1 and waits for it to  terminate.   The  system’s
       one  time  tasks  are  done  here.   /etc/runit/1  has  full control of
       /dev/console to be able to start an emergency shell  if  the  one  time
       initialization tasks fail. If /etc/runit/1 crashes, or exits 100, runit
       will skip stage 2 and enter stage 3.

STAGE 2

       runit runs /etc/runit/2, which should not return until system shutdown;
       if   it  crashes,  or  exits  111,  it  will  be  restarted.   Normally
       /etc/runit/2 starts runsvdir(8).  runit is able to handle the ctrl-alt-
       del keyboard request in stage 2, see below.

STAGE 3

       If  runit  is  told  to  shutdown  the  system,  or stage 2 returns, it
       terminates stage 2 if  it  is  running,  and  runs  /etc/runit/3.   The
       systems  tasks  to  shutdown and possibly halt or reboot the system are
       done  here.   If  stage  3  returns,   runit   checks   if   the   file
       /etc/runit/reboot  exists  and has the execute by owner permission set.
       If so, the system is rebooted, it’s halted otherwise.

CTRL-ALT-DEL

       If runit receives  the  ctrl-alt-del  keyboard  request  and  the  file
       /etc/runit/ctrlaltdel  exists  and  has the execute by owner permission
       set, runit runs /etc/runit/ctrlaltdel, waits for it to  terminate,  and
       then sends itself a CONT signal.

SIGNALS

       runit only accepts signals in stage 2.

       If  runit  receives a CONT signal and the file /etc/runit/stopit exists
       and has the execute by owner permission set, runit is told to  shutdown
       the system.

       if  runit  receives  an  INT signal, a ctrl-alt-del keyboard request is
       triggered.
