假设已经chroot到slitaz目录：
查看一下当前目录结构，其中rootfs,是解压rootfs.gz后修改的目录，修改好的rootfs.gz已经拷贝到rootcd/boot目录下。
其中rootcd就是整个LiveCD,mount 之后拷贝出来的所有文件。
  /media/sdb7/pjq/slitaz # ls
  chroot_in_env.sh  rootcd            rootfs
用来创建ISO的命令：  
<code>
  /media/sdb7/pjq/slitaz # genisoimage -R -o slitaz-pjq-hacked.iso -b  boot/isolinux/isolinux.bi
n  -c boot/isolinux/boot.cat -no-emul-boot -boot-load-size 4  -V "SliTza-Hacked by pjq" -input
-charset iso8859-1 -boot-info-table rootcd              
Size of boot image is 4 sectors -> No emulation

可以看到生成的ISO文件变大了，之前只有30M，这是因为我安装了mplayer,vim,scim-pinying
