This is what I use on systems using systemd (*ubuntu 16.04, 18.04, 
Debian Stretch)

# setup mythtv-backend.service startup delay
In a terminal on the machine running mythtv backend:

sudo systemctl edit mythtv-backend.service # and add the following three 

# Delay mythbackend startup to allow network and tuners to fully stabilise
ExecStartPre=/bin/sleep 20

Then exit from the edit screen (it uses nano by default, so Ctrl+x, then
y, then Return key) then  reboot the machine
