如何使用自动安装进行最小安装？

Question

我正在尝试使用 Ubuntu 服务器 20.04 LTS AMD64 iso 映像构建具有自动安装功能的自定义 Ubuntu 映像。我必须如何配置才能user-data执行最小安装？

Answer 1

抱歉，没有答案（如果您找到答案，请回复），但一个丑陋的解决方法是在自动安装用户数据中使用后期命令来删除尽可能多的内容，以便在安装后进行缩小。文档中似乎没有任何内容，源代码中只有一个引用，在我无法破译的示例文件中：https: //github.com/canonical/subiquity/blob/206b7ae678bc1993e1eef46c74efb12f30dbbb43/examples/install-来源.yaml

Answer 2

我会用这样的东西。

用户数据：

仅供参考：我目前正在开发具有几种不同配置文件/变体的通用用户数据。现在我正在与持久的环境变量和迟到的命令作斗争
