但这不是最近的问题。就这样“有一段时间了”——抱歉。
我有三个网络设备，我的网络需要 8 秒以上才能启动。

8.590s systemd-networkd-wait-online.service
我有一个wait-online添加--any标志的覆盖 - 我理解这意味着在第一次成功连接后将满足在线等待。

ExecStart=/usr/lib/systemd/systemd-networkd-wait-online --any
我有三个 systemd.networkd 文件
> ls /etc/systemd/network/*.network
/etc/systemd/network/100-eno1.network - onboard ethernet
/etc/systemd/network/200-usb01.network - usb-ethernet
/etc/systemd/network/500-wlan0.network - wifi
我的理解是 systemd 按词法顺序读取这些文件 - 100,200,500 对吗？
然后这个日志片段显示，在读取 100 个文件之前，这 8 秒的大部分时间都花在了与 wifi 和 USB 以太网作斗争上，然后后板载以太网已启动，我们正在等待 wifi，然后等待 USB 以太网。

我希望先读取 100 个文件，然后在启动后启动系统eno1。
我的理解错误在哪里？如何更正配置？
答案1
ExecStart在设置覆盖之前，您必须清除该参数。例如：
[Service]
ExecStart=
ExecStart=/usr/lib/systemd/systemd-networkd-wait-online --any
参考这个回答
希望这可以帮助。
