on debian systems there is a /etc/init.d/skeleton file which is a template you 
can use as a starting point. See also man update-rc.d for more infos on how 
to setup startup scripts. Don't do it by hand! As the skeleton is quite 
complex, for a simple startup action you can use something like this (just be 
aware that it may be called several times depending on the runlevel(s) you 
choose) :

. /lib/lsb/init-functions
case "$1" in
	start)
		log_daemon_msg "Doing something"
		# do it...
		log_action_end_msg 0
	;;
esac

You may also have a look at /lib/lsb/init-functions which contains some system 
functions often used in startup scripts.
