Initscript issues-Yocto

Hello,

I am trying to call a script at booting time . So , as per my knowledge i have created a script & kept it inside poky/meta/initscript folder & changed the recipe file for it accordingly ,so that run level links will be created .Everything works fine ,but the daemons which i called from that script are not running automatically at the boot time.

Basically i need bluetooth & wpa_supplicant daemons to be called at boot time.

When i run manually "./update-rc.d myscript.sh defaults" ,its working fine.But i need it to be done automatically at booting.

Any suggestion regarding this.

Thanks & regards
Surya
