Ubuntu Snappy Core

Snappy Ubuntu Core is a new rendition of Ubuntu with transactional updates - a minimal server image with the same libraries as today’s Ubuntu, but applications are provided through a simpler mechanism. The snappy approach is faster, more reliable, and lets us provide stronger security guarantees for apps and users.

Through Snappy, Canonical has partnered with Erle Robotics to bring Ubuntu and the app store to the world of robotics.
