我正在尝试创建一个具有预定义程序和设置的 ubuntu 服务器安装媒体。为此，我使用 Cubic。通过 chroot 终端，我可以安装我需要的所有软件，而且效果很好。
我还想使用一些预定义设置（例如用户和密码等）定制安装屏幕，并且希望在安装过程中不会请求这些信息。
为此，我创建了一个预置，其设置是我想要自动进行的，并在 grub 中添加了 FILE = / cdrom / preseed / mv.seed 和 auto = true 的启动参数，但是当我尝试安装时，这些设置仍会继续出现。
因为我使用 UEFI 启动，所以我知道提交的是文件 /boot/grub/grub.cfg 来选择我的安装，而不是 /isolinux/txt.cfg
有人知道为什么预种子没有加载吗？

# d-i partman-auto / disk string / dev / sda
# In addition, you'll need to specify the method to use.
