Though I wanted the service to hang around so that it could continually monitor the system. So if the system becomes degraded at any point, the LED will turn red (and vise-versa).

Hmm, that's a very good question. Other than suggesting to write a small service that waits for the StartupFinished bus signal I have no good suggestion I fear. That service could start any time, would just wait for the signal, and do what you want it to do, and exit then...

Try adding a .service with "Type=idle" and add it to your default target (usually multi-user.target). This should run the unit after the system is booted (i. e. running or degraded).

[systemd-devel] When System is Degraded
I'm using systemd in an embedded device that some some LEDs. I'd like to make an LED red when the system starts up degraded, and green when everything is working normally. I'm having a hard time figuring out where to fit this in. I tried using a service that runs "systemctl is-system-running" after I've reached my target, but that command returns "starting", obviously. What's a better way to run a command when the system is "running" vs "degraded"?___ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel
