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.
