Linux FromScratch项目简称LFS，它提供必要的步骤，帮你一步一步地创建自己定制的Linux系统。关于为什么有人希望安装一套LFS系统，我们可以给出很多的理由。人们问得最多的问题是，既然可以下载到一份成型的套件比如Debian或者RedHat，为什么还要去争论从头开始手工安装一份Linux系统呢？这是一个很合理的问题，我将问答你。LFS存在的最重要的原因就是教给人们一个Linux系统其内部是如何工作的。自己创建一份LFS系统将让你了解到Linux工作的每个细节，以及它们是如何彼此依赖和协同工作的。最重要的在于，你可以按自己的喜好和需求定制它。

Beyond Linux From Scratch (BLFS) is a project that provides instruction for extending a Linux From Scratch (LFS) installation into a full desktop or server distribution. The first release candidate for version 6.3 has been released: "BLFSversion 6.3 is the complement to the LFS 6.3 book. The BLFS book nowprovides build and configuration instructions for almost 500 packages(many more than that if you want to count each individual package inthe auto-tooled X Window instructions). Some of the new packagesintroduced in this version are: Dash, ksh, D-Bus bindings, Wireshark,rxvt-unicode, Gutenprint, Pidgin, GnuTLS (and many of itsdependencies), Qt version 4.x, GnuPG version 2.x, and Amarok.
