[mythtv-users] delaying backend startup until the network is up

[James Abernathy]

Well, I’ve now tested the use of:

[Unit]
After=network-online.target
Wants=network-online.target

in my /etc/systemd/system/mythtv-backend.service.d/override.conf file.  This is without any full-internet.service enabled and no wait-until-pingable.py script.

It appears that it worked correctly from boot (at least the first time). I’ll reboot some more times to confirm.

The order of starting is Network Manager Wait Online, and Mythtv Backend happened the same second, but in the right order. 2 seconds later I get the first mythhdhrrecorder tuner message.  All tuners are online and working. Below is a portion of the syslog:
