/etc/network/interfaces 没有声明主网络接口

正在考虑建立一个桥接网络我从 Wi-Fi 切换到有线连接。然而，我的网络与描述不同：

$ cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

我可以并且应该添加The primary network interfaceas描述？

一般参考：

/etc/network/interfaces 的正确语法是什么？

桥接器在启动时未从 DHCP 服务器获取 IP
