    Disallow changing of system props during install
    
    Changing of system properties require a reboot and rebooting the machine
    in the middle of an installation/live session is not a good idea. More so
    since we track end of installation/live session through number of
    reboots, especially in case of live session where we automatically remove
    the machine on shutdown/reboot if no installation was performed.
