现在下面来进一步描述整个光盘的制作过程：
(一). kickstart文件
    kickstart文件可以借助系统中的system-config-kickstart工具来生成，或是手工编写，通常生成后的文件命名为： ks.cfg，并存放在光盘的根目录下。以下为我的ks.cfg文件，有点长，为了方便，我安装了所有的软件包。
# Kickstart file automatically generated by anaconda.

install
cdrom
key --skip

keyboard us
xconfig --startxonboot
network --device eth0 --bootproto dhcp --hostname rhel53

    在ks.cfg文件中，我把分区这块注释掉了，主要是有时分区会有一些变化，也便于在新机或是新硬盘上安装，这块还是手动为好。

(二). isolinux.cfg文件:
default autoinstall 
prompt 1
timeout 50
display boot.msg
F1 boot.msg
F2 options.msg
F3 general.msg
F4 param.msg
F5 rescue.msg
label autoinstall
  kernel vmlinuz
  append ks=cdrom initrd=initrd.img
label linux
  kernel vmlinuz
  append initrd=initrd.img
label text
  kernel vmlinuz
  append initrd=initrd.img text
label ks
  kernel vmlinuz
  append ks initrd=initrd.img
label local
  localboot 1
label memtest86
  kernel memtest
  append -

与光盘的文件相比，主要是修改了等待时间，改为5秒（timeout 50),以及增加了三行：
label autoinstall
  kernel vmlinuz
  append ks=cdrom initrd=initrd.img

（三).生成光盘
    建一个临时目录，将光盘上所有文件都cp到这个临时目录下，并删除文件TRANS.TBLT和isolinux/boot.cat.别忘了把ks.cfg文件放到目录当中，并修改isolinux/isolinux.cfg文件，生成光盘教程的命令如下：

# rm  TRANS.TABL  isolinux/boot.cat
# chmod  +w  isolinux/*
# mkisofs  -o  ../RHEL-autoinstall-dvd.iso  -J  -r  -v -R \
   > -b  isolinux/isolinux.bin  -c  isolinux/boot.cat  \
   > -no-emul-boot  -boot-load-size  4  -boot-info-table  \
   > -V  "My RHEL"  \
   > .
# cd ..
# implantisomd5  --force  ./RHEL-autoinstall-dvd.iso
implantisomd5程序，RHEL并不包含它，可以从如下地址下载译，并安装它。http://www.rocklinux.net/sources/misc/isomd5sum/
