How to build a new root file system?

[lakshmi pathi]

Hi,
I'm trying to create new root file system for my kernel.
How to do that? Any documentation links ?


I have spent some time with Linux From Scratch - but messed somewhere?
Should i process with LFS again ?

I'm trying to find a solution for question posted here.
