I have a PC running Mythbuntu which has an LCD which I had a bit of a struggle getting going under systemd. However using Type=forking it is now working fine. However reading the man page for systemd.service is says that it is recommended to use PIDFile. I have tried adding PIDFile=/run/LCDd.pid but this causes an error message:- LCDd.service - LCDd Loaded: loaded (/etc/systemd/system/LCDd.service; enabled; vendor preset: enabled) Active: activating (start) since Tue 2018-02-13 09:49:03 GMT; 1min 8s ago Process: 2485 ExecStart=/usr/sbin/LCDd -c /home/steve/lcd/LCDd.conf (code=exited, status=0/SUCCESS) CGroup: /system.slice/LCDd.service └─2487 /usr/sbin/LCDd -c /home/steve/lcd/LCDd.conf Feb 13 09:49:03 mythbuntu systemd[1]: Starting LCDd...

I have tried creating LCDd.pid in /run with root:root but get the same. How is the pid file generated? Am I right in thinking that LCDd is so old that it hasn't been written with systemd in mind so does not support PIDFile?
