I built a customized (somewhat stripped, then other things added) LFS back in April, 2009. It's based on the 6.3 LFS live CD with packages updated to the 6.4 book (current at the time).
The LFS live CD is a very good starting point. I haven't explored other (even more stripped) alternatives like tinycore. Here's what I posted about it the last time this question was raised: http://linuxfromscratch.org/pipermail/lfs-support/2009-November/036881.html You can fetch my "build it" sources (that is, the updated makefiles, my notes, etc.) from http://msbit.com/osdv/osdvlfs.tgz -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
