# Basic idea : This runs dbus-monitor which waits for
# "RebootRequested" memberf from com.canonical.Unity.Session ,
# which apprears only when the user clicks the shutdown option
# from the Unity's top right drop down box. Why RebootRequested ?
# Because this message is guaranteed to pop up once user presses
# the shutdown button.
# The while loop with read command does the big job.
# dbus-monitor sends initial message , so we want to filter only
# The output that contains the string we need, hence the case...esac
# structure employed here. Once we get the proper message.
# we check whether update-manager or package managers are running
# If there is one instance, then call CancelAction method
# and send notification to the user.
# Both dbus-monitor and while loop run continuously. This
# can be launcher as script in `/etc/rc.local` or `/etc/rc2.d`
# or preferably (!) in `/etc/xdg/autostart/` .
# Here is sample /etc/xdg/autostart/preventShutdown.desktop file
#
# [Desktop Entry]
# Type=Application
# Name=Prevent-Update
# Exec=/home/$USER/bin/preventShutdown.sh
# OnlyShowIn=GNOME;Unity;
# Terminal=false
#
# Remember to make this file as well as script be root-owned with
# chmod +x /path/to/Script.
# It is preferred to store the script in user's personal $HOME/bin
# folder.
# Make sure to edit $HOME/.profile file to include that into $PATH
# variable
