# Goals I want systemd to know if a service is up when it's up I want systemd to know if a service is down when it's down If a service crashes I want drkonqi as before /ideally/ we want systemd handling the restarts as it's a lot smarter than our internal app method, but that's something we can itterate on. # Current state ExecStart=/opt/kde5/bin/plasmashell causes drkonqi to work, plasma to restart, but systemd thinks the process is degraded and down ------- ExecStart=/opt/kde5/bin/plasmashell -n Restart=always causes plasmashell to restart, but we don't get drkonqi :( >Mar 27 12:15:12 david-desktop systemd[703]: plasmashell.service: Succeeded. >Mar 27 12:15:12 david-desktop systemd[703]: plasmashell.service: Consumed 6.242s CPU time. >Mar 27 12:15:12 david-desktop plasmashell[77501]: org.kde.drkonqi: The specified process does not exist. --------- ExecStart=/opt/kde5/bin/plasmashell -n Restart=on-failure Doesn't work, even though it should. On sending SIGSEGV systemd receives sigterm, because kcrash meddles with it. We also still don't get drkonqi

# Goals I want systemd to know if a service is up when it's up I want systemd to know if a service is down when it's down If a service crashes I want drkonqi as before We ideally want systemd handling the restarts as it's a lot smarter than our internal in-app method # The cause of the bug right now We use the DBus name to know when a service is up. We definitely want this. However, implicitly that also determines when a process is stopped. As plasmashell (for example) crashes the bus name is lost. Then the entire cgroup is killed in order to restart, which would include any drkonqi
