What is the best way to setup myth for power saving?
We have one Fedora box with frontend and backend on it and a network connected HDHomeRun for a tuner on DVB. Completely turning this box off is not really an option but letting the disk, tuner and network connection sleep would be good. Looking at top, the backend is constantly using about 15% of my CPU. This is because of EIT crawling? We get around 8 days of guide data so we don't need it going all night. It also locks up both the tuners, it would be nice if it only used one for this.
It looks like when the frontend idles it should allow the backend to shutdown until a recording is due?
I can't even see how the backend is stop / started. There is a systemd unit file for the backend but it doesn't seem to be controlling it. The documentation seems to predate systemd.
Any hints or ideas on how this should be setup?

Hi,
Not sure why you'd be willing to sleep drives etc. but not shutdown
the system. Have you been to:
https://www.mythtv.org/wiki/ACPI_Wakeup
It's a long read and has a Fedora section. Plus, it works.
As to backend start/stop, I've seen eveything from SystemV (/etc/init.d), Upstart (*buntu),
systemd and even /etc/rc.local (ugh.) If you haven't: systemctl status myth*
