Puppet
當 puppet 控制的文件將被 yum 更改時通知
當包含由 puppet 控制的文件的包即將更改該文件時，是否可以在控制台上收到通知？意思是，在 yum 中進行 yum update 時，是否可以注入自定義警告？
Yum 支持外掛，因此完全可以編寫一個外掛來讀取記憶體的 puppet 清單並在事務將覆蓋 puppet 控制的文件時發出警告。我不知道現有的外掛可以做到這一點，但我可能會自己寫一個，因為我喜歡這個想法。
該外掛檢查所有新安裝/升級/降級的軟體包，告訴您它將覆蓋哪些 puppet 管理的文件，並要求確認這樣做。

2013 年 11 月 8 日更新：
正如評論中所暗示的，我現在已經把它變成了一個更大的項目，以改善 Yum 和 Puppet 之間的互動。你可以在 GitHub 上找到它。
