You generate an ephemeral runtime unit in /run but you then try to enable it in /etc. To make it easier to help, you should give us an idea/overview what you are trying to achieve. What you did so far (and why), what environment you are using etc. It's really hard to give you a good answer when we don't even tell us the systemd version and distro you are using. -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth? ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel
