CentOS kickstart安装光盘制作

1,编辑光盘根目录下isolinux/isolinux.cfg文件加入要引导的选项
2,然后就是光盘根目录下ks.cfg文件的配置
3,boot:linux ks=cdrom:/ks.cfg 或 boot:ks 来引导
4,关于kickstart文件，可以利用system-config-kickstart工具生成，也可参照/root/anaconda-ks.cfg文件进行修改，
要注意的是如果是从光盘安装，kickstart的%post会运行于chroot模式，无法直接从光盘复制文件到目标系统，可在%post后添加--nochroot解决，详见下面链接
