After nearly 20 hrs,now i have my distro minimal (LFS 6.4) :)
But it has size of around 800MB. How to reduce it's size?
Is it possible to create minimal distro less than 100MB
or even 50 MB with LFS itself or should I use busybox?

If you want to go uber-small ( <100MB ) , then I'd use busybox for all the utilities that I could get away with. Only if I needed some special feature of a utility that the busybox version doesn't offer (or there is no applet for it) would I then use the standard version. Also, look into uClibc, instead of glibc - it is geared for embedded systems. That will save you a lot of space, and Busybox works fine with it.
