Snappy Ubuntu Core
Snappy Ubuntu Core takes the absolute minimum of files and code necessary for a usable Ubuntu server image and adds to it a new means of managing software packages. The idea is similar to how smart phones like Android-based phones provide software. In this method, the software packages include everything they need to run on the operating system, effectively making it so that a package is isolated from the operating system more completely. This is designed to protect from the possibility of a package breaking other packages or an entire operating system installation. It is also intended to make updates easier and cleaner. With the idea of convergence, where Ubuntu is aiming to use the same set of software for traditional desktops, laptops, tablets, and phones, all these devices will share the core operating system and Unity interface, and packages that work on any one should also work on the others. This feature first appeared in Ubuntu 16.04 LTS.
