我尝试使用 netboot 和 preseed.cfg 从 Ubuntu 18.04 安装最小桌面。我在 preseed.cfg 中添加了以下行：ubiquity ubiquity/minimal_install boolean true，但它没有安装最小安装，它仍然安装完整版本。netboot 映像amd64 - For 64-bit Intel/AMD (x86_64)从此 URL 下载：http://cdimage.ubuntu.com/netboot/18.04/

这preseed.cfg幅画仍然包含
tasksel tasksel/first multiselect ubuntu-desktop
这将安装完整的 Ubuntu 桌面系统（任务组）。删除该行并重试。
