### BEGIN INIT INFO
# Provides:
# Required-Start: $remote_fs $syslog
# Required-Stop: $remote_fs $syslog
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: Start daemon at boot time
# Description: Enable service provided by daemon.
### END INIT INFO
#
# A copy of other initd templates with some notes.
#
# Instructions:
#
# To set up a script, add the running directory, command,
# and user to the variables immediately below this comment.
# You'll want to save this template as the name of the service
# it's controlling. Also, verify init.d is on your machine!
# `ls /etc/init.d` should show the other scripts.
#
# Then:
# sudo cp <this-script> /etc/init.d
# sudo chmod +x /etc/init.d/<this-script>
# sudo update-rc.d <this-script> defaults
# sudo update-rc.d <this-script> enable
# sudo echo 'id:2345:respawn:/bin/sh /path/to/application/startup'
#
# If you've done everything right you could call
# sudo service <this-script> start
# and your service will be on.
#
# Try rebooting your machine and see if your service comes up.
