找不到有ifupdown的桥接装置

Question

请注意，我使用的是Void。

这是我的/etc/network/interfaces.d/br0文件：

auto br0
iface br0 inet dhcp
    bridge_ports eth0
    bridge_stp off
        bridge_waitport 0
        bridge_fd 0

但是，在引导时，我得到了以下错误：

我已经确认我已经安装了bridge-utils。我不知道这里的问题是什么。我会很感激你的帮助。

(这确实是一个“评论”，不是和回答，但它不适合在评论部分)

ifup似乎没有创建“场景背后”的桥接界面。

我希望它这样做：

ip link add name brLAN type bridge
ip link set brLAN up
ip link set eno1 master brLAN
ip link set eno1 up

如果桥梁使用dhcp，那么：

dhclient brLAN
