systemd 说“networking.service failed”但网络已启动

通常，我使用 openrc init 运行 Gentoo，但正在安装 Debian 10 服务器并且在理解系统时遇到一些困难。服务器通过自定义 dracut initrd 启动，该启动创建了绑定网络接口，然后从 iscsi 根启动。那部分一切正常。启动时会出现三个接口及其各自的网络：192.168.1.0/24、10.0.0.0/24 和 172.16.0.0/24。

我的（小）问题是 systemd 提供以下信息：

# systemctl --failed
  UNIT               LOAD   ACTIVE SUB    DESCRIPTION
● networking.service loaded failed failed Raise network interfaces

我认为这主要是由于其中一个网络在初始化时处于活动状态。在Gentoo中，我可以将一个接口标记为不提供网络服务。 systemd 是否有类似的概念，或者是否有我遗漏的设置？同样，所有接口实际上都已启动并正常工作（2 个网桥，1 个绑定），我已经剪掉了本地接口以及绑定和网桥中的 NICS。

解决了！

我在 /etc/network/interfaces 中定义了两个网关。一旦我删除了除一个之外的所有内容，错误就得到了纠正。

# systemctl --failed
0 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.
