Build an embedded Linux distro from scratch tutorial

In this tutorial, you learn about cross-compiling, the boot loader, file systems, the root file system, disk images, and the boot process, all with respect to the decisions you make as you're building the system and creating the distribution.

Build an embedded Linux distro from scratch tutorial:
- Discussion of cross-compilation issues
- Review of the components of a Linux system and how they are put together
- Detailed steps for building, installing, and configuring the target system

Build an embedded Linux distro from scratch tutorial Objectives:
This tutorial shows you how to install Linux on a target system. Not a prebuilt Linux distribution, but your own, built from scratch. While the details of the procedure necessarily vary from one target to another, the same general principles apply. The result of this tutorial (if you have a suitable target) is a functional Linux system you can get a shell prompt on.

This tutorial assumes that your shell is a Bourne shell derivative; if you use a C shell derivative, the prompt will probably look different, and you will need to use different commands to set environment variables.
