FreeBSD系统下创建DVD.iso安装光盘

<p>准备刻一张FreeBSD-7.0-RELEASE的DVD，网上很多介绍都是在Windows下使用什么iso提取工具的，貌似很麻烦。参考了一些FreeBSD高手的实现，我写了一个简单的脚本，主要功能是从3张disc*.iso创建出一个dvd.iso<br />
<br />
1，准备工作：<br />
工作目录 work/ 和 3张disc*.iso, 比如<br />
work/<a href="ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386/ISO-IMAGES/7.0/7.0-RELEASE-i386-disc1.iso" target="_blank">7.0-RELEASE-i386-disc1.iso</a><br />
work/<a href="ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386/ISO-IMAGES/7.0/7.0-RELEASE-i386-disc2.iso" target="_blank">7.0-RELEASE-i386-disc2.iso</a><br />
work/<a href="ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386/ISO-IMAGES/7.0/7.0-RELEASE-i386-disc3.iso" target="_blank">7.0-RELEASE-i386-disc3.iso</a><br />
<br />
2，用以下代码创建脚本文件，比如 mkdvd.sh，放在work目录下。用root用户执行，将在work目录下产生一个7.0-RELEASE-i386-dvd.iso的文件。<br />
