Which type of LFS should I choose on 64bit system

[Phillip Huang]

Hello folks,

I want to build LFS on my new 64bit platform(Intel EM64T), and I googled CLFS, 
while according to another link: http://lwn.net/Articles/243695/

JH said the x86_64 LFS LiveCD was available in July 30,2007, and the above 
link provide download address. However, I do not find any relevant manual 
about how to install this x86_64 LFS. 

Is the step as same as build common LFS in 32bit? And what's the difference 
between this LiveCD with CLFS?

Any suggestion or comment would be appreciated.

Kindly Regards,
Phillip
