Embedded Linux Distributions

Introduction
Besides the Linux kernel, one of the advantage of embedded Linux is the ability to leverage hundreds if not thousands of existing free and open source packages to easily and quickly add new features to devices. These packages range from graphical libraries, multimedia libraries, network libraries, cryptographic libraries, network servers, infrastructure software and more. However, integrating all these components together requires a relatively deep knowledge of the components. Hence, embedded-specific distributions and build systems have been created to ease this process.
