Ubuntu JeOS (pronounced "juice") is a discontinued variant of Ubuntu that is described as "an efficient variant ... configured specifically for virtual appliances." It is a concept for what an operating system should look like in the context of a virtual appliance. JeOS stands for "Just enough Operating System."
