How could you add in your deb to respring your device after package is installed? So once in cydia you install your package it says respring. Thats what i wanna add in my deb. If i rember right i need something to say respring springboard. Been a while since ive done that but want to add that to something.

You need to add a postinst script file to your package. Eg: https://github.com/mattlawer/NCCleaner/blob/master/layout/DEBIAN/postinst
