现在的DVDROM挺便宜的，我们可以应用一个脚本，把我们下载的ISO文件刻成DVD镜象文件，具体方法如下：

　　1、 下载以下脚本：

　　源码:#/bin/bash

　　# by Chris Kloiber <ckloiber@redhat.com>

　　# 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.

　　if [ $# -lt 2 ]; then

　　echo "Usage: `basename $0` source /destination/DVD.iso"

　　echo ""

　　echo " The 'source' can be either a directory containing a single"

　　echo " set of isos, or an exploded tree like an ftp site."

　　exit 1

　　fi

　　cleanup() {

　　[ ${LOOP:=/tmp/loop} = "/" ] && echo "LOOP mount point = \/, dying!" && exit

　　[ -d $LOOP ] && rm -rf $LOOP

　　[ ${DVD:=~/mkrhdvd} = "/" ] && echo "DVD data location is \/, dying!" && exit

　　[ -d $DVD ] && rm -rf $DVD

　　}

　　cleanup

　　mkdir -p $LOOP

　　mkdir -p $DVD

　　if [ !`ls $1/*.iso 2>&1>/dev/null ; echo $?` ]; then

　　echo "Found ISO CD images..."

　　CDS=`expr 0`

　　DISKS="1"

　　for f in `ls $1/*.iso`; do

　　mount -o loop $f $LOOP

　　cp -av $LOOP/* $DVD

　　if [ -f $LOOP/.discinfo ]; then

　　cp -av $LOOP/.discinfo $DVD

　　CDS=`expr $CDS + 1`

　　if [ $CDS != 1 ] ; then

　　DISKS=`echo ${DISKS},${CDS}`

　　fi

　　fi

　　umount $LOOP

　　done

　　if [ -e $DVD/.discinfo ]; then

　　awk '{ if ( NR == 4 ) { print disks } else { print ; } }' disks="$DISKS" $DVD/.discinfo > $DVD/.discinfo.new

　　mv $DVD/.discinfo.new $DVD/.discinfo

　　fi

　　else

　　echo "Found FTP-like tree..."

　　cp -av $1/* $DVD

　　[ -e $1/.discinfo ] && cp -av $1/.discinfo $DVD

　　fi

　　rm -rf $DVD/isolinux/boot.cat

　　find $DVD -name TRANS.TBL | xargs rm -f

　　cd $DVD

　　mkisofs -J -R -v -T -o $2 -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table .

　　/usr/lib/anaconda-runtime/implantisomd5 --force $2

　　cleanup

　　echo ""

　　echo "Process Complete!"

　　echo ""

　　2、然后运行

　　# mkdvdiso.sh /path/to/the/cd/isos /location/and/name/of/dvd.iso

　　# growisofs -Z /dev/scd0=/location/and/name/of/dvd.iso
