Ubuntu JeOS


Ubuntu JeOS (pronounced "juice") is a discontinued variant of Ubuntu that is described as "an efficient variant ... configured specifically for virtual appliances."[1][2] It is a concept for what an operating system should look like in the context of a virtual appliance.[3] JeOS stands for "Just enough Operating System." JeOS has been replaced by Ubuntu Core, which is now an officially supported minimal variant of Ubuntu.
