是否有一个systemctl命令来启动一个服务，recursion（在它之前）它需要的所有依赖关系？
我有时间了
> systemctl start service2 A dependency job for service2.service failed. See 'journalctl -xe' for details. > journalctl -xe Aug 10 09:06:21 ... systemd[1]: Dependency failed for service 2 Service. -- Subject: Unit service2.service has failed -- Defined-By: systemd -- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel -- -- Unit service2.service has failed. -- -- The result is dependency. Aug 10 09:06:21 ... systemd[1]: Job service2.service/start failed with result 'dependency'.
并且必须find完整的依赖关系树并且开始每手一个接一个的服务… p.ex.
> systemctl start service1
