The shutdown mechanism is modular. You can use various methods (choosen 
at compile time). The default is to use the xfsm_shutdown_helper_sudo.c. 
For your case, you could simply modify the xfsm_shutdown_helper_redhat.c 
and edit the test in the xfsm_shutdown_helper_spawn() method. You need 
to select your method at configure using --with-shutdown-style=<whatever>.
