Ticket 49099 - resolve systemd startup interaction with ns
    
    Bug Description:  In systemd, it expects our process to stay in
    the foreground. Due to a mistake, I put config parsing after
    systemd parsing, which meant that we over-wrote the setting
    
    Fix Description:  Move systemd notify processing to after
    command line processing.
