runit-services

Runit init configuration for VectorLinux. It features process supervision, logging, services startup in parallel between others. It starts the system using three stages. In stage 1 runit runs the one time scripts, for tasks like mounting the filesystems and running checks. Stage 2 starts the system daemons. The runit command drives this stage, it is started with PID 1 until the system is down. Stage 3 controls the system shutdown.

Install

Get the runit package from vlcore repository for 7.1. This will install the binary files. Then install this package for the configuration:

make install

For installing in an alternative root:

make install DESTDIR=<root>

Runlevels

There are 3 runlevels: safe starts syslog and crond plus 6 instances of mingetty. The tui runlevel adds common services on top of safe. The _desktop_ runlevel adds the necesary bits for starting an X Desktop (dbus and friends and GDM.) For switching runlevels use runsvchdir.

Services

Runit uses one directory for each daemon. They are located in /etc/sv. The run file inside the service directory controls the daemon startup. The daemon needs to run in the foreground and its output is logged to /var/log. Services can be controlled through the sv command line tool:

sv start <service name>

For enabling a service create a symlink from the service directory in /etc/sv to the proper runlevel directory. For example, this enables sshd in the desktop runlevel:

ln -s /etc/sv/sshd /etc/runit/runsvdir/desktop

Reboot and Shutdown

Use init 0 for shutdown and init 6 for reboot.

Using with sysvinit

You can try runit without removing sysvinit. Boot the system passing init=/sbin/runit-init to the kernel. Do not use the initrd since it needs to be modified for runit. With LiLo you can hit tab for achieving this. If you use Grub, select the kernel you want to boot and press e. Add the option to the linux line.

Documentation

The runit package installs documentation into /usr/doc. You can also visit the runit home page: http://smarden.org/runit/. Runit was written by Gerrit Pape.
