If running a program as unprivileged user, you need to make sure that it has access to all the resources it needs. Try sticking: d /run/programd2 0755 programd2 programd2 - - in /etc/tmpfiles.d/programd2.conf and changing the unit file to have: PIDFile=/run/programd2/programd2.pid and updating the configuration for the program to actually write there.

Also note, that systemd is not creating any PID file, it is just your daemon that does that. In general, we recommend getting rid of the need of all PID files, as they are an outdated and pretty broken concept; they are not needed at all with systemd, just minimally supported by it, as legacy, for stuff that still needs it. |

Example service file [Unit] Description=Daemon After=syslog.target network.target [Service] Type=forking User=programd2 Group=programd2 PIDFile=/var/run/programd2.pid ExecStart=/usr/sbin/programd2 -D [Install] WantedBy=multi-user.target I need to start service from the user. Also must have a pid file. But if i use User= Group= not able to create pid file in /var/run (No permission). In logs: PID file /var/run/programd2.pid not readable (yet?) after start. I believe that this is a problem systemd. Systemd should create pid as "root" and do it chown before Exec. This is a very bad decision: >> ExecPre=touch /var/run/program.pid >> ExecPre=chown programd2:programd2/var/run/program.pid >> Exec=/bin/su -s /bin/sh -c '/usr/sbin/programd2 -D' programd2
