Shell腳本+Kickstart文件定制CentOS 6

寫了一個腳本（見下面的鏈接），利用kickstart文件 + 腳本來生成自動安裝的ISO， 基於CentOS 6的，在CentOS 6.2下測試沒問題，估計CentOS 6.*都沒什麼問題

這個腳本的最大的特點就是不需要CentOS的官方原版ISO鏡像，所有需要的文件都是通過網絡下載，有的是從sohu的鏡像源，有的是163的（分散壓力，呵呵） 這樣做的還有一個好處就是安裝的rpm包都是最新的，進入系統之後，不需要yum -y update了 （適合有潔癖的人）

然後，rpm包都是通過yum安裝，這裡我安裝了一個yum的插件，達到只下載不安裝的目的，另外就是用yum的時候，還指定了一個--installroot的參數，讓yum不去讀本機的數據庫，如果不加這個參數，就不能順利的下載本機已經安裝過的包

ks.cfg是用system-config-kickstart生成的kickstart配置文件，如果沒有這個命令，就yum -y install system-config-kickstart來安裝一下就行，也可以通過修改本地/root目錄下的ananconda-ks.cfg，但需要注意的是這個文件裡面有一行需要注釋掉或者刪除掉
repo --name="CentOS" --baseurl=cdrom:sr0 --cost=100
如果不注釋，安裝的時候，ananconda會找這個yum源
