Atom Linux is an open source project still in early starting phase. Its purpose is to give the user a way to easily create a robust and secure embedded Linux system. The user downloads a bootstrap image, then configures the utilities (servers…) and libraries needed by its custom code. Except its own code, he doesn’t need to do any compilation, the system automatically downloads prebuilt packages from the Atom Linux server. The Atom Linux system is built with robustness and security in mind. Among other features, it provides secured multi-partitioned update system and power supply fault tolerance.
