To learn how to create a minimal linux system read these articles :
Also take a look at this :
All these documents talk about creating a system using only busybox inside
initramfs which is a root filesystem that gets passed as a parameter to the
kernel by the boot loader. All of the examples use a very simple script to
start the system, this is the basic concept used in the Tiny Core linux(
To really understand the LFS init scripts(or any other big initialization
script collection) you have to learn bash programming first, a good
introductory reading is : http://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO.html.
When I did my first LFS build I also wanted to understand linux
initialization, and reading LFS init scripts was hard without bash
background, so I decided to rebuild LFS using only bash scripts, its a great
way to learn bash and how to organize large bash programs.
