to learn "linux from scratch"
normally i DO NOT recommend a real physical book for linux
BUT LFS IS DIFFERENT
BUY $$$ the current book!!!
grab the current e-book and put it on a handheld tablet or e-book reader
then treat LFS manual as a textbook for a self taught class
and i do mean
use a pad of paper and a #2 pencil to wright a install outline
in reality you ARE writing a masters/php theses outline
this WILL be your guide ( your BIBLE -- if you will )
but keep in mind
LFS is not a "new to linux Operating system"
if you are new
then think of it as a PHD Doctorate level collage course of study
and you do not yet have even a 2 year associates
