Target 也有自己的配置文件。

$ systemctl cat multi-user.target[Unit]Description=Multi-User SystemDocumentation=man:systemd.special(7)Requires=basic.targetConflicts=rescue.service rescue.targetAfter=basic.target rescue.service rescue.targetAllowIsolate=yes

注意，Target 配置文件里面没有启动命令。

上面输出结果中，主要字段含义如下。

Requires字段：要求basic.target一起运行。
Conflicts字段：冲突字段。如果rescue.service或rescue.target正在运行，multi-user.target就不能运行，反之亦然。
After：表示multi-user.target在basic.target 、 rescue.service、 rescue.target之后启动，如果它们有启动的话。
