packageManagerEnd.sh

#!/bin/bash

#
# this script handles the actions AFTER PackageManager.py exits
#	that can not be easily performed while it is running:
#
#	uninstalling SetupHelper and therefore the PackageManager service
#
#	system reboots are also handled here since that needs to happen
#	AFTER SetupHelper is uninstalled
#
#	GUI restart if needed
# 
# this script is called from PackageManager.py just prior to it exiting
#
# PackageManager will pass the following options as appropriate:
#
#	'shUninstall'	to uninstall SetupHelper
#	'reboot'		to trigger a system reboot
#	'guiRestart'	to trigger a GUI restart
#
#	all are optional but at least one should be passed or
#	this script will exit without doing anything
#
#	reboot overrides a guiRestart since the reboot will restart the GUI
