New RancherOS Offers Lean Linux Functionality Within Docker Containers (rancher.com)

RancherOS is a lean Linux distribution aiming to offer "the minimum necessary to get Docker up and running," and tucking many actual Linux services into Docker containers. An anonymous Slashdot reader quotes Distrowatch: Josh Curl has announced the release of a new version of RancherOS [which] moves the project out of its alpha status and introduces new features, including an official Raspberry Pi image... "We're especially excited about this since it offers users a cheap method of getting started with Docker and RancherOS."

No, it's lightweight virtualization / jail

Docker is basically the fastest, lightest type of virtualization. Mainly it gets you a reasonably secure jail. The container contains the entire userland, the whole OS other than the kernel. Some people use this to run both Debian Linux and Android at the same time. Yeah dependencies are handled too, but that's not normally the point.
