[root@localhost html]# rsync -a --exclude=Packages centOS6 centOS6.32bit/

[root@localhost html]# pwd

/var/www/html

[root@localhost html]# mkdir centOS6.32bit/Packages

复制软件包

1

参考嵌入式linux的方法

比如debian的base系统安装，只有200M左右，无显示，只有最基本命令

后续缺什么自己安装 apt-get install XXX

完全定制化，没有多余的东西

完全使用串口登陆

桌面等窗口控制器有需要也是可以后装的

以前做过相关设备就是这么搞得，低配硬件，速度嗖嗖的，

祝你成功哈
