The stated purpose of Linux From Scratch is slightly different from that of "a distro." It is an important difference.
The first and foremost purpose of LFS is education.
Each and every part of a complete, somewhat-minimal Linux installation is presented in source-code form and you use your existing Linux installation to "bootstrap" your way to a complete, stand-alone system. (Or,
you can use the LiveCD as your host system, which is actually a rather cleaner way to go about it.)
LFS is not
the easiest way to "get started with Linux." That
is what a more-conventional "distro" is all about
: to provide an essentially turn-key installation of a fairly-generic Linux kernel, and oodles of interesting "extras," that can be installed on almost-any computer with a very-good chance of success.
suggest that if you are new to Linux, you start with a different, separate
machine from the one you now have (e.g.
to run Windows with, or to run 'production' Linux with...), and get or download a commercial "distro," and start with that. This will plunge you into the Linux environment quickly, completely, and relatively safely. Then, in due time,
as you become comfortable with 'packages' and the basics of system management, you can explore LFS.
you start with LFS, you should practice things like compiling and installing an application from source-code, and maybe also you should recompile your existing Linux kernel. When you are comfortable with those things, read
LFS manual before you consider actually doing what it says.
The experience of actually doing it, however, is priceless. Here, right at your fingertips, is a complete production-grade operating system environment, and you can
"build it from scratch" right in the privacy of your own home. (Where no one can hear you
