[App_rpt-users] Simpleusb question

In the note - http://ohnosec.org/drupal/node/193 In configuration of simpleusb the following line is mentioned - touch /etc/init.d/simpleusb I presume this is just to put a zero length file marker at this location? Is this needed? What references this? Does simple USB need to be a service in any derivative of app_rpt - zaptel/dahdi ? 73 Doug WA3DSP http://www.crompton.com/hamradio
