How to Build Your Own Linux Distribution
Shelly writes "Go to the source to learn Linux basics and build the right Linux for you. Linux From Scratch (LFS) and its descendants represent a new way to teach users how the Linux operating systems work. LFS is based on the assumption that compiling a complete operating system piece by piece not only teaches how the operating system works but also allows an independent operator to build systems for speed, footprint, or security."
found a great primer: http://www.ccoss.org/tutorials/lfs/Linux_from_Scra tch_A_Tour.htm
People have been doing LFS for years. It's nothing really too new or significant.
It's not even a really good way to learn about how "Linux the OS" works. It's just another way of spending an inordinate amount of time tinkering with your computer (not that there's anything wrong with that).
If you want the benefits of LFS without the pain, just stick with Gentoo or Sorcerer Linux and let someone else worry about the sources. You still get the custom compilation benefits but don't have to waste time trying to track down stupid dependency problems (at least not as much as you would with LFS, but more than with a mainstream distro).
Building your own Linux distribution is like building your own airplane.
People build their own airplanes not because they want Airplane X or Feature Y, they do it because they want to build an airplane. They want to take control of the construction process and be intimately familiar with the final product. They want to learn how the various airplane systems function. They will not necessarily learn the detailed workings of an internal combustion engine, but they will learn how it interacts with other systems.
The same is true with LFS. If you want a generic Linux distribution, then install Fedora, Gentoo, Debian, or whatever suits you. However, if you want to build your own Linux distribution, if want to take control and be intimately familiar with the final product, then LFS is the way to go. You will learn how the various components function. You will not necessarily learn the detailed workings of the Linux kernel, but you will learn how it interacts with other system components.
