debconf-get-selections 中的哪些值不应被预置?

debconf-get-selections 中的哪些值不应被预置?

我想在新系统的安装中复制针对我的系统当前配置所做的 Debian 安装选择。

Debian 可以通过“预配置”(又名“preseed”)文件进行预配置,该文件基本上包含安装程序将提出的问题的答案。

文档指出从现有 Debian 安装创建预配置文件的一种方法是:

...使用debconf-get-selectionsdebconf-utils 包将 debconf 数据库和安装程序的 cdebconf 数据库转储到单个文件中:

$ debconf-get-selections --installer > file
$ debconf-get-selections >> file

但它随后立即补充道:

但是,以这种方式生成的文件将包含一些不应预置的项目......

该文档没有详细说明那些不应预置的项目是什么。

有人可以详细说明一下吗?


作为说明,下面我包含了从上面两个命令获得的输出的第二个字段,其中我只保留了以 开头的行d-i以及注释,有时为了简洁而被截断。 (只保留以开头的配置行的原因d-i是在预配置文件示例由 Debian 提供,仅出现此类行。)

简短回答

来自专门用于 DI 预置的 Debian wiki 页面

不要处理 debconf-get-selections (--installer) 生成的 preseed.cfg,而是从中获取值并用它们修改示例 preseed 文件。

预置示例Debian 提供的文件应该足以启动,但您可以在同一 wiki 页面上找到许多由不同的人出于不同目的提供的其他预置文件。

少简答

在您发布的 debconf 问题列表中,每个带有注释“供内部使用”而没有“可以预置”的问题不应被预置。

但是许多其他 debconf 问题可能无法通过预置文件预先回答,例如与硬件相关的问题(如果您想在不同的硬件上运行安装)、记录一些自动配置失败或成功的问题(这可以在某些特殊情况下可以预先设定,但可以毫无问题地通过自动过程来回答)。

debconf-get-selections 的输出包含许多大多数人从未见过并且(不应该)关心的自动回答问题。随着时间的推移,随着新的硬件、软件、更好的检测或新的可能性的出现,这种自动选择正在发生变化。重要的是要尽可能少地接触自动配置,以便从 debian-installer 的所有改进中受益,并能够随着时间的推移和不同的硬件将预置文件所需的更改保持在最低限度。
