当包含由puppet控制的文件的包即将更改该文件时,是否可以在控制台上收到通知？这意味着,在yum做yum更新时,是否可以注入自定义警告？

Yum支持插件,因此完全可以编写一个读取缓存的puppet清单的插件,并在事务覆盖木偶控制的文件时发出警告.我不知道有一个现有的插件可以做到这一点,但我可能会写一个自己写的,因为我喜欢这个想法.

该插件会检查所有新安装/升级/降级的软件包,告诉您它将覆盖哪些木偶管理的文件,并要求确认这样做.

该插件本身可以找到in my github hacks repository.

2013年11月8日更新：

正如评论中暗示的那样,我现在把它变成了一个更大的项目来改善Yum和Puppet之间的互动.你可以找到它on GitHub.
