That did not work for me:

mythuser at amethi:/var/log/mythtv$ sudo systemctl cat mythtv-backend.service
# /lib/systemd/system/mythtv-backend.service
[Unit]
Description=MythTV Backend
Documentation=https://www.mythtv.org/wiki/Mythbackend
After=mysqld.service network.target

[Service]
User=mythtv
EnvironmentFile=-/etc/mythtv/additional.args
ExecStart=/usr/bin/mythbackend --quiet --syslog local7 $ADDITIONAL_ARGS
StartLimitBurst=10
StartLimitInterval=10m
Restart=on-failure
RestartSec=1

[Install]
WantedBy=multi-user.target

# /etc/systemd/system/mythtv-backend.service.d/override.conf
[Unit]
After=NetworkManager-wait-online.service

and after reboot:

ythuser at amethi:/var/log/mythtv$ systemctl status mythtv-backend

I guess I don't understand why network manager has to start if mysql and 
mythbackend are on same machine.
