Why does postinst script for tweak app cause app icon dispear?

Question

I make a tweak app works inside backboardd, so backboardd has to be restarted after the tweak is installed.I used the script below in DEBIAN's postinst to restart backboardd. It works right for me, but lead to a new problem: it respring automatically at the end of the installation without the "Restart SpringBoard" button click in Cydia, and for that, there don't show the app icon on the home screen except you reboot the device entirely.What can I do for that?

#!/bin/sh

launchctl stop com.apple.backboardd

Answer 1

Cydia does kill backboardd and you don't have to do it yourself.
