utmpset(8)                                                    System Manager's Manual                                                   utmpset(8)

NAME

       utmpset - logout a line from utmp and wtmp file

SYNOPSIS

       utmpset [ -w ] line

DESCRIPTION

       The utmpset program modifies the user accounting database utmp(5) and optionally wtmp(5) to indicate that the user on the terminal line has
       logged out.

       Ordinary init(8) processes handle utmp file records for local login accounting.  The runit(8) program doesn't include code  to  update  the
       utmp file, the getty(8) processes are handled the same as all other services.

       To enable local login accounting, add utmpset to the getty(8) finish scripts, e.g.:

        $ cat /service/getty-5/finish
        #!/bin/sh
        exec utmpset -w tty5
        $

OPTIONS

       -w     wtmp. Additionally to the utmp file, write an empty record for line to the wtmp file.

EXIT CODES

       utmpset returns 111 on error, 1 on wrong usage, 0 in all other cases.

runit(8)						      System Manager's Manual							  runit(8)

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 shut-
       down the system.

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