CentOS 7 kickstart 文件，将条目添加到 /etc/hosts

CentOS 7 kickstart 文件，将条目添加到 /etc/hosts

我有一个 CentOS 7 kickstart 文件，大部分情况下运行良好。该%packages部分失败，因为我需要向 /etc/hosts 添加一个条目，以将 mirrorlist.centos.org 指向我们公司内部的存储库。我可以%post毫无顾虑地在该部分中添加该条目，但它似乎在软件包之后运行。我尝试将其添加到该%pre部分，但它从未出现在 /etc/hosts 中。根据文档，pre 部分在安装开始之前运行，所以我猜文件系统甚至还不存在。我可以将软件包移动到该%post部分并直接运行yum install <my package>，但我认为使用软件包部分会更简洁一些。这是我的完整 kick start 文件：

根据@HBruijn 提供的信息，我只想回答我自己的问题。似乎 packages 部分仅用于从安装媒体安装软件包。这很合理，因为在操作系统安装阶段，您通常不会使用外部存储库。通常，您会先安装操作系统，然后再安装其他软件包。因此，为此使用 post 部分很合理。在那里，很容易添加条目/etc/hosts，然后安装其他软件包。
