This is just a configuration issue. You must tell systemd to export some 
touchscreen and Qt related environment variables to all new processes it 
executes.

From the old INITV days the script is located in "/etc/init.d" and a link 
exists in "/etc/rc.d/" pointing to this script. The name of the link defines 
the order to execute this script at runtime.

Install the script itself to "/etc/init.d" with the help of 
PTXdist's "install_copy/install_alternative" macro and create the link 
with "install_link":

   @$(call install_alternative, [...], 0, 0, 0644, /etc/init.d/yourscript)
   @$(call install_link, [...], ../init.d/yourscript, /etc/rc.d/S99yourscript)

Regards,
Juergen
