Ack! No no no no no! At least put something this critical in a password protected database, not a place that could possibly be written to by a malicious user that gains access to an easily-writable directory like /tmp, the DoS and security ramifications of having a system like this are huge. Be exceptionally careful, and never pretend that /tmp is a safe place for data. If something is being read from /tmp then it should be treated the same way user-inputted data is, and never trusted.

Thanks I believe this has been answered quite recently and the large consensus was to have a daemon (cron or otherwise) check for some status file or database entry, which when set it would perform the required function. So for instance to reboot the machine, perhaps a cron job would check for the existence of /tmp/myFrontEnd/reboot and if found reboot the machine. Thus the front end would only need to create the file.
