Thank you Antoni! that sounds easy enough. Creating the file in the Myth 
shutdown sounds good. I will probably sip it, because I don't have NFS 
on the router. Nor do I have the'at' package, I'll look for it and if 
not then I will just check the date in the cron job and wake up the Myth 
Backend if it's time and delete the file. Thanks for the help.
