I have a daemon which runs for a pre-configured period of time and then quit. User can restart it if needed after that. It seems that systemd cannot handle this type of service. Below is the service file I tried.
[Unit]
# DaemonXXX quits
Description=DaemonXXX
After=network.target
[Service]
Type=forking
PIDFile=/var/run/daemonXXX.pid
ExecStart=/usr/local/sbin/daemonXXX
StandardOutput=journal
[Install]
WantedBy=multi-user.target
I can start service with above unit file. After the daemon quits, I'm also able to start it again by command systemctrl start DaemonXXX. But when the service quit after timeout, systemd complains that system is degraded because daemonXXX quits. If I add RemainAfterExit opton to [Service] section,
[Unit]
# as above
...
[Service]
# as above
...
RemainAfterExit=yes
...
systemd will not complain of degrarded system but I am no longer able to restart the service again by command systemctrl start daemonXXX as systemd assumes that daemonXXX is running correctly and there is no need to restart it. Is there a way to solve it?
