自动:也就是说，它们在系统启动或服务启动时自动启动第一次被调用
如果设置为自动，它将在您登录之前启动.但是有时可能会依赖于其他服务来启动您的服务.这可能就是延迟启动的原因.

automatic : that is, they start automatically when the system starts or when the service is called for the first time
if you set automatic it will start before you log in. but sometimes there may be dependencies on other services to start your service. That may be the reason to delay on start.
