First impressions of KaOS 2014.04 KaOS is a Linux distribution which draws a good deal of its design from the Arch Linux project. KaOS is a rolling-release distribution and maintains a narrow focus to achieve its goals of creating "a tightly integrated rolling and transparent distribution for the modern desktop, built from scratch with a very specific focus." KaOS focuses exclusively on providing one desktop environment (KDE), for one hardware architecture (x86 64-bit) and most included applications are based on the Qt toolkit. If this list of characteristics sounds familiar it may be because the Chakra project has similar goals and blueprints and KaOS even borrows some technology from the Chakra project. There are differences, however. Where Chakra maintains a semi-rolling release platform, updating end-user software regularly while keeping the base operating system relatively static, KaOS takes a pure rolling-release approach, keeping its users on the cutting edge. The download image for KaOS is approximately 1.7 GB in size.
