Add an init script?

Here's an easy one: what's the right way to add an init script under /etc/rc.d/init.d (Fedora)? I assumed Fedora just enumerated and ran every file in that directory at bootup but it does not appear to work that way. I got my scripts to run by hijacking the bluetooth one to call them but obviously this isn't the Right Way.

If the script is in /etc/init.d and it's header follows a LSB convention for this, it can be set to start at boot time at the pre-defined run-levels, by running "chkconfig name-of-init-script on" (or off). Check chkconfig man page for other options.

chkconfig will read the following header of init script to figure out what run-levels it should run and what are the dependencies for other services. For example, the festival init script has the following header:

Code:

### BEGIN INIT INFO
# Provides:          festival
# Required-Start:    $syslog $remote_fs
# Should-Start:      $time
# Required-Stop:     $syslog $remote_fs
# Should-Stop:       $time
# Default-Start:     3 5
# Default-Stop:      0 1 2 6
# Short-Description: festival daemon providing full text-to-speech system
# Description:       Start festival to allow applications to access a
#       text-to-speech system with various APIs, as well as an environment
#       for development and research of speech synthesis techniques. It is
#       written in C++ and has a Scheme-based command interpreter for
#       general control. 
### END INIT INFO

chkconfig will create or remove the right links at /etc/init.d/rc[0123456S].d as needed.
