systemctl 状态 systemd-networkd 显示为死亡

我正在进行 Debian 测试/strech。我在看debian 用户可以通过 systemd-networkd 连接到网络吗？ 并做了同样的事情。

[$] cat /etc/systemd/network/wired.network

[Match]
Name=eth0

[Network]
DHCP=ipv4
DNS=8.8.8.8
DNS=8.8.4.4

[DHCP]
RouteMetric=10%   


[$] sudo systemctl start systemd-resolved

[$] sudo ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf

[$] sudo systemctl enable systemd-networkd systemd-resolved

Created symlink /etc/systemd/system/multi-user.target.wants/systemd-networkd.service → /lib/systemd/system/systemd-networkd.service.
Created symlink /etc/systemd/system/sockets.target.wants/systemd-networkd.socket → /lib/systemd/system/systemd-networkd.socket.
Created symlink /etc/systemd/system/multi-user.target.wants/systemd-resolved.service → /lib/systemd/system/systemd-resolved.service.

[$] sudo mv /etc/xdg/autostart/nm-applet.desktop /etc/xdg/autostart/nm-applet-desktop

最后——

[$] sudo systemctl status systemd-networkd

● systemd-networkd.service - Network Service
   Loaded: loaded (/lib/systemd/system/systemd-networkd.service; enabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:systemd-networkd.service(8)

知道这里出了什么问题吗？为什么 systemd-networkd.service 显示为死亡？

更新 - 重新启动系统并不得不 -

$ sudo ifdown eth0

进而 -

$ sudo ifup eth0

然后这两件事就完美地展现出来了——

[$] sudo systemctl status systemd-networkd

我想这已经成功了。该系统是一个过时的工作站，因此主板上没有无线网络芯片，芯片本身也没有支持，因此没有做任何事情wpa_supplicant。

[Resolve]

然后输入：

$ systemctl start  systemd-resolved.service 
$ systemctl status systemd-networkd systemd-resolved
