一旦系统启动并初始化，systemd 就是第一个启动的进程之一。我们想要启动的任何程序或软件都将作为 systemd 的子进程启动。这意味着它由systemd控制，但会作为自己的进程运行（尽管共享systemd的资源），以便我们更容易识别等

For example, once a system boots and it initialises, systemd is one of the first processes that are started. Any program or piece of software that we want to start will start as what’s known as a child process of systemd. This means that it is controlled by systemd, but will run as its own process (although sharing the resources from systemd) to make it easier for us to identify and the likes.
