## 选择系统 (以 x86_64 为例)
Target System -> x86
Subtarget -> x86_64

## 选择固件的文件系统
## https://openwrt.org/docs/techref/filesystems
Target Images -> squashfs

## 选择构建 x86_64 的 GRUB 固件
Target Images -> Build GRUB images (Linux x86 or x86_64 host only) 

## 选择更小的压缩格式固件，方便复制
Target Images -> GZip images

## 修改软件包可用空间，默认安装会占用 100M 左右，建议修改扩大，为后续安装其他软件打基础
Target Images -> Root filesystem partition size

## 添加web界面 (y 键选择、 n 键排除)
LuCI > Collections -> Luci

## 添加兼容性依赖
LuCI > Modules -> luci-compat

## 添加中文
LuCI > Modules -> Translations -> Chinese Simplified

## 添加 openclash、zerotier
LuCI > Applications -> luci-app-openclash
LuCI > Applications -> luci-app-zerotier

## 添加主题
LuCI -> Themes

## 添加wget
Nerwork -> File Transfer -> wget-ssl

## 添加 kmod-tun，TUN 模式必须
Kernel modules -> Network Support -> kmod-tun

## 排除 dnsmasq，由于默认会安装 dnsmasq-full，这里需要排除 dnsmasq，否则会冲突报错。
Base system -> dnsmasq
