前文回顾：  
我们上一章《[系统裁剪之旅（4）——启动克隆后的系统][4]》中完成了使用克隆盘启动系统的操作，本章将会把之前全部的操作囊括到自动化安装脚本当中。以方便后续制作安装盘是使用。

本章内容：  
以脚本的方式实现系统自动化安装。

安装脚本：

install\_system.sh

#!/bin/sh
    
    HD="sda"
    IType=2
    cdrom=hdc
    
    echo -e "\v\tStart The Installation Of OS7.9 X86_64"
    echo ""
    IType=""
    
    if [ "$IType" = "2" ]
    then
    echo ""
    echo -e "\v\tStart The Installation Of OS7.9 X86_64"
    
    sleep 3
    echo "" 
    Hname=1
    
    echo "Re-partition the disk..."
    
    #disk fenqu

            swapon    /dev/${HD}2
    fi

第5行“cdrom=hdc”的hdc为存放上一章中“boot.tar.gz”和“rootfs.tar.gz”的磁盘，我这里的“hdc”指向的是光驱。“boot.tar.gz”和“rootfs.tar.gz”这两个压缩包需要放到“/dev/hdc/IMAGES/”目录下。
