I hate to be cruel, but it's advice like this which made sysvinit the 
slow, clunky nightmare that it was. Why five seconds? If the database is 
ready, why wait? What if the database is doing repairs, will five 
seconds be enough?

The following should be a suitable start:

	Description=the open source DVR, MythTV



This should start mythtv when you log in (WantedBy) and kill mythtv when 
you log out (BindsTo). Save this as /etc/systemd/system/mythtv at .service, 
then run "systemctl enable mythtv@:0.service" for display :0.
