Ordering dependencies are between jobs. To have any effect here systemd must have both start jobs queued concurrently. What is unexpected is that multiple services are apparently submitted as individual independent jobs, not as single "transaction". I am not sure even if there is method to start multiple units concurrently. > Is this behavior documented somewhere? The systemctl behavior? Not to my best knowledge, at least explicitly. _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel
