很久之前就下载了LFS的一些资料，也做过一段时间，但是当时没坚持，现在把台式机弄好了，打算再完整的做一次LFS，下载的ISO是6.3，参考的资料是：
http://www.linuxsir.org/bbs/thread322894.html
我在这做一个自己的记录。
我不是用虚拟机装的 ，在自己的硬盘后面留了12G做LFS，用CD启动后运行cfdisk分区，分区完成后就开始做一些必要的准备工作。
挂载目标分区到/mnt/lfs；
在/mnt/lfs下面建立一下几个文件夹：
sources:存放源码
tools:工具链
prepare:我自己加的，用于存放一些恢复步骤的文件，主要有：
begin.sh:root用户时使用的一些初始化脚本，代码如下：

这样，恢复就显得简单多了。
