KaOS 2015.04.14

http://sourceforge.net/projects/kaosx/

KaOS is an open source Linux distribution built around the KDE Plasma Workspaces and Application project, as well as the pacman package manager software from the Arch Linux operating system.
Distributed as a 64-bit Live DVD

The system is distributed as a single Live DVD ISO image that supports only 64-bit hardware platforms. It can be written to a blank DVD disc with any CD/DVD burning software, or a USB flash drive using the UNetbootin application.

KaOS is completely independent and provides users with a rolling-release system, which will make sure that their installations will always be up-to-date without requiring them to download a new ISO image and upgrade the entire OS.
