這篇文章是對之前博文的一點擴展和補充：

這裏主要是在之前的基礎上添加了一些自己制作好的程序，還有安裝openssh7.5版本，直接全部包含在鏡像中，並且設置一些自啟動程序、DNS、還有計劃任務之類的，都是利用ks.cfg文件的post字段後面定義的腳本實現的，在post的階段中使用--nochroot 表示可以使用任何目錄，而本階段中的 / （根目錄）是會自動掛在到/mnt/sysimage下，下面請看我的ks.cfg文件：

#platform=x86, AMD64, or Intel EM64T

這個裏面包括使用了最新的openssh 7.5 版本，裏面也有一些走過的坑。。不過最終還是做出來了

對Centos的自動安裝的補充
