I there first thanks for any help you can give me.

I am using a TP-Link TL-WR842ND with the ATTITUDE ADJUSTMENT (0.2, r32522).

I am building a custom image to my needs.
And I have to make some scripts to run on boot.
So I checked the http://wiki.openwrt.org/doc/techref/initscripts and I managed to put a script to run on boot.

But now I do not rely know how to do to make the image that I am building to have this script enabled from the start.
I can put it in /etc/init.d by putting the script in /files on my trunk folder, but that does not make it enable.

Where can I define that my script that is in init.d is enable on the image?
