runit-init(8) System Manager's Manual runit-init(8)
NAME
init - a UNIX process no 1
SYNOPSIS
init [ 0 | 6 ]
DESCRIPTION
runit-init is the first process the kernel starts. If runit-init is started as process no 1, it runs and replaces itself with runit(8).
If runit-init is started while the system is up, it must be either called as init 0 or init 6:
init 0 tells the Unix process no 1 to shutdown and halt the system. To signal runit(8) the system halt request, runit-init removes all
permissions of the file /etc/runit/reboot (chmod 0), and sets the execute by owner permission of the file /etc/runit/stopit (chmod
100). Then a CONT signal is sent to runit(8).
init 6 tells the Unix process no 1 to shutdown and reboot the system. To signal runit(8) the system reboot request, runit-init sets the
execute by owner permission of the files /etc/runit/reboot and /etc/runit/stopit (chmod 100). Then a CONT signal is sent to
runit(8).
EXIT CODES
runit-init returns 111 on error, 0 in all other cases.
