Embedded Linux Distributions
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.

Special purpose embedded Linux distributions
- Flash Linux - a distribution specifically for USB keys and Live CDs
- Eagle Linux - http://www.safedesksolutions.com/eaglelinux/
- An embedded Linux distribution aimed at helping users learn Linux by creating bootable Linux images "virtually from scratch". Eagle Linux 2.3 is currently distributed as a concise, 26-page PDF documenting the creation of a minimalist, network-ready Linux image for bootable CDs, floppies, or flash drives. See description at: http://ct.enews.deviceforge.com/rd/cts?d=207-106-2-28-5560-8662-0-0-0-1
- uClinux A distribution targeting (but not only) systems without Memory Management Unit. See also UClinux Shared Library.
Configuration and Build systems
- Open Embedded - System for building full embedded images from scratch
- Buildroot is a set of Makefiles and patches that makes it easy generate a cross-compilation toolchain and root filesystem for your target Linux system using the uClibc C library.
- Linux From Scratch
- LTIB - Linux Target Image Builder (by Stuart Hughes of FreeScale) - see http://savannah.nongnu.org/projects/ltib
- OpenBricks - Embedded Linux Framework
- OpenBricks provides a set of packages, patches and shell-based rules that creates a toolchain and a rootfs with customized packages and features selection.
- Currently supports x86_32, x86_64, PowerPC, PowerPC64 and ARM architectures with either uClibc, Glibc or eGlibc C library.
- Building Embedded Userlands - Presentation by Ned Miljevic & Klaas van Gend at the ELC 2008 which compares different configuration and build systems. Video of the conference available.
- Scratchbox Cross-Compilation Toolkit, with support for x86 and arm.
