自从得知可以使用Github Actions 云编译OpenWrt固件后，喜出望外，再也不需要在本地Ubuntu里折腾了，还可避免因无法全局科学出国而引起的编译失败。
首先需要fork大佬的固件，也可clone后自行修改，然后再push到GayHub。
我这里选择Lienol定制的Lean-Lede固件：
修改workflow
修改/.github/workflow/下的yml文件，可以直接复制下面我修改后的workflow。
此处关键在于固件定制部分的自定义。
使用make menuconfig 选择好相关配置后，将 /.config 中相应的配置条目复制到workflow中固件定制部分的对应位置。
下面是我修改后workflow，已编译成功，链接

# ========================固件定制部分========================
#
#
# 如果不对本区块做出任何编辑, 则生成默认配置固件.
#
# 以下为定制化固件选项和说明:
#
#
# 有些插件/选项是默认开启的, 如果想要关闭, 请参照以下示例进行编写:
#
# =========================================
# | # 取消编译VMware镜像: |
# | cat >> .config <<EOF |
# | # CONFIG_VMDK_IMAGES is not set |
# | EOF |
# =========================================
#
#
# 以下是一些提前准备好的一些插件选项.
# 直接取消注释相应代码块即可应用. 不要取消注释代码块上的汉字说明.
# 如果不需要代码块里的某一项配置, 只需要删除相应行.
#
# 如果需要其他插件, 请按照示例自行添加.
# 注意, 只需添加依赖链顶端的包. 如果你需要插件 A, 同时 A 依赖 B, 即只需要添加 A.
#
# 无论你想要对固件进行怎样的定制, 都需要且只需要修改 EOF 回环内的内容.
