To make your Startscript LSB conform, there are only a few things to do. Your Script need the following informations:

- Provide at-least ‘start, stop, restart, force-reload, and status’ - Return Proper exit code - Document run-time dependencies

You can put these informations in a header like this one:

### BEGIN INIT INFO
# Provides: my_daemon
# Required-Start: postgresql networking
# Required-Stop: postgresql networking
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: This is a test daemon
# Description: This is a test daemon
# Name: your_name
# Build-Date: date
### END INIT INFO

For ruby-startscripts here is an example:

#!/usr/bin/env ruby
#
### BEGIN INIT INFO
#
# Startup script for gmetric from Sebastian Gleicher
# description: gmetric is the Ganglia Custom Metric Utility
# rubyboot_gmetric_daemon.rb is a start-script for gmetric-daemon
# Version Date 30.11.2012
#
# Provides: rubyboot_gmetric_daemon.rb
# Required-Start: $network $syslog
# Required-Stop: $network $syslog
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: starts the rubyboot_gmetric_daemon
# Description: starts the rubyboot_gmetric_daemon to control the gmetric
# utility
#
# chkconfig: 2345 80 20
#
#!/usr/local/bin/gmetric_gpu.rb_controller
#
### END INIT INFO

APP_NAME = 'rubyboot_gmetric_daemon.rb'
APP_DIR = '/etc/init.d'

ARGV.each do|a|
puts "Argument: #{a}"
end

require 'daemons'

options = {
:dir_mode => :system,
:monitor => true
}

if ['start'].include? ARGV.first
puts "Starting gmetric-daemon"
Daemons.run('/var/lib/gmetric/gmetric_gpu.rb',options)
end

if ['stop'].include? ARGV.first
puts "Stopping gmetric-daemon"
Daemons.run('/var/lib/gmetric/gmetric_gpu.rb',options)
end

if ['restart'].include? ARGV.first
puts "Restarting gmetric-daemon"
Daemons.run('/var/lib/gmetric/gmetric_gpu.rb',options)
end

unless %w{start stop restart status}.include? ARGV.first
puts "Usage: #{APP_NAME} {start|stop|restart}"
end

exit
