runit - use with traditional init

It's possible to use runit's service supervision without replacing the init scheme of the system. Simply run the stage 2 of runit as a service with your current init.

Normally this is done by either adding an entry for /sbin/runsvdir-start to /etc/inittab, or by adding /sbin/runsvdir-start as command to /etc/rc.local, or by adding /sbin/runsvdir-start to the system's StartupItems.

In any case, you first need to copy the stage 2 script to /sbin/runsvdir-start, and create the services directory /var/service/:

 # install -m0750 /package/admin/runit/etc/2 /sbin/runsvdir-start
 # mkdir -p /var/service

How to use with sysvinit
How to use with *BSD init
How to use with MacOSX init

Using with sysvinit

If your system uses a sysvinit alike init scheme with a /etc/inittab file, do:

 # cat >>/etc/inittab <<EOT
 SV:123456:respawn:/sbin/runsvdir-start
 EOT

and tell init to re-read its configuration, e.g.:

 # init q

Using with *BSD init

If your system uses a BSD alike init scheme with a /etc/rc.local script, do:

 # cat >>/etc/rc.local <<EOT
 csh -cf '/sbin/runsvdir-start &'
 EOT

and reboot your system.

Using with MacOSX init

On MacOSX 10.2 create an entry for runit in /System/Library/StartupItems/:

 # cd /System/Library/StartupItems
 # mkdir -p runit
 # cp -p /package/admin/runit/etc/macosx/StartupItems/* runit/

and reboot your system.
