Hello,
Sorry if this question is a bit basic for a devel list, I tried asking it in a
ubuntu forum but
didn't get any views, let alone replies.
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...
Feb 13 09:49:03 mythbuntu systemd[1]: LCDd.service: PID file /run/LCDd.pid not
readable
(yet?) after start: No such file or directory
steve@mythbuntu:~$
Removing the line PIDFile=/run/LCDd.pid in LCDd.service and all is good.
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?
