# 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 `/service/`:

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

How to use with MacOSX init

## Using with sysvinit and inittab

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 sysvinit and upstart

If your system uses a sysvinit alike init scheme that utilizes upstart instead of inittab, and which has start and stop scripts located in `/etc/event.d`, do:

     # cat >/etc/event.d/SV <<\EOT
     # for runit - manage /sbin/runsvdir-start
     start on runlevel-2
     start on runlevel-3
     start on runlevel-4
     start on runlevel-5
     stop on shutdown
     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.

On MacOSX 10.4 create an entry for runit in `/Library/LaunchDaemons/`, and tell launchd to start the new service:

     # cp /package/admin/runit/etc/macosx/org.smarden.runit.plist \
         /Library/LaunchDaemons/
     # launchctl load /Library/LaunchDaemons/org.smarden.runit.plist
