This will make sure the HDHR's are up and has the side affect of
delaying 'til the network is up:

#!/bin/sh -

ATTEMPTS=20
LOG="/tmp/hdhomerun_config.log"
SLEEP_TIME=2

echo "\nStarting check for HD Homerun: $(date). " >> $LOG

for i in $(seq $ATTEMPTS); do
     hdhomerun_config discover 2>&1 >> $LOG
     if [ $? -eq 0 ]; then
         echo "HD Homerun is up at: $(date)." >> $LOG
         exit 0
     fi
     sleep $SLEEP_TIME
done

echo "Couldn't find the HD Homerun in $(expr \( $SLEEP_TIME + 1 \) \* $ATTEMPTS) seconds!" >> $LOG
exit 1

Then copy /lib/systemd/system/mythtv-backend.service to
/etc/systemd/system/mythtv-backend.service. Then add a line
like: ExecStartPre=wherever.you.put.the.script.above
to the file just copied. Do: sudo systemctl daemon-reload
Start the backend again as usual, e.g.
sudo systemctl start mythtv.backend

Don't forget to make the script executable.

If you don't want to verify that the HDHRs are up, just add:
ExecStartPre=/usr/bin/nm-online --quiet --timeout=5
Make sure you have nm-online 1st (server distributions don't.)
