RHEL DVD光盘制作方法

    Fedora Core系列早已提供DVD(ISO)下载，而使用最广泛的RHEL系列，却依然是4张CD,

安装时要不停的更换光盘。安装结束后，如果再安装某个RPM包，就更加让人头疼，经常是4张光盘

都找个遍才能找到。

    以前看到过Redhat的一个工程师写的CD转DVD的script, 使用起来非常方便。RHEL每发布一个Update,

我都制作一个同样的DVD. 为了避免这个脚本丢失，特纪录如下.

■1. 使用方法

     convert2dvd.sh dir dvdfilename

     ①dir: 存放RHEL 4个ISO文件的目录

     ②dvdfilename , 比如 RHEL4U4_DVD.iso

■2.script ( convert2dvd.sh)

# 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.
