you find all startupscript in rc[runlevel].d/ mostly they reference to the init script in init.d but you can e.g. write a minmal shellscript on that you reference from rc[runlevel].d which calls the init script with your "switches". The standard runlevel is 3 (no x stuff)
What you need is update-rc.d (install and remove System-V style init script links) command. Using man you will see very usefull examples
