把RedHat企业Linux 5 cd版合成dvd版的脚本

时间：2007-03-26 来源：心跳男人

经合并后，在vmware中以该dvd.iso启动，并正常安装了rhel5.
用法: ./script.sh /TheCdIsoPath   /home/username/dvd.iso

#!/bin/bash

# A quick hack that will create a bootable DVD iso of a Red Hat Linux
# Distribution. Feed it either a directory containing the downloaded
# iso files of a distribution, or point it at a directory containing
# the "RedHat", "isolinux", and "images" directories.

# This version only works with "isolinux" based Red Hat Linux versions.

# Lots of disk space required to work, 3X the distribution size at least.

# GPL version 2 applies. No warranties, yadda, yadda. Have fun.
