We first try to use the newer "SRST" extension for rebooting and shutting down and if that fails, we try to shutdown using the legacy "System Shutdown" extension (which can't reboot, so we always shutdown). The kernel will halt, if we return from here due to all attempts at rebooting / shutting down failing.
