安装后运行自定义脚本
%post 在系统安装后执行
--不带参数，其实就是在真实的操作系统里操作。
--nochroot 已安装的真实操作系统被挂载到内存虚拟操作系统中的/mnt/sysimage目录。这个参数的用途主要是配合%pre使用的。先将光盘里的文件copy到内存运行的虚拟操作系统，再从内存虚拟操作系统copy到已安装的真实操作操作。
%post --nochroot
mkdir /media
mount /dev/cdrom /media/
cp /media/test1.txt /mnt/sysimage/root/
%end
这篇文章是对之前博文的一点扩展和补充：
这里主要是在之前的基础上添加了一些自己制作好的程序，还有安装openssh7.5版本，直接全部包含在镜像中，并且设置一些自启动程序、DNS、还有计划任务之类的，都是利用ks.cfg文件的post字段后面定义的脚本实现的，在post的阶段中使用--nochroot 表示可以使用任何目录，而本阶段中的 / （根目录）是会自动挂在到/mnt/sysimage下，下面请看我的ks.cfg文件：

这个里面包括使用了最新的openssh 7.5 还有 openssl1.01t 版本，里面也有一些走过的坑。。不过最终还是做出来了
