Proper service dependency won't even attempt to start dependent service until dependencies are known to run. systemd already propagates some unit types (devices, mounts and swaps) from system to user instance. Are there any fundamental problems that prevent doing it for other types? _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel
