KaOS is a desktop Linux distribution, featuring the latest version of the KDE desktop environment and other popular software programs that use the Qt toolkit. It was originally based on Arch Linux, but since April 2013, developers started creating their own packages, which are now available from Kaos’s own depot. KaOS uses a roll publishing development model and is only for 64-bit computer systems.
KaOS has made the choice to use the Linux kernel as a base (though the Illumos kernel is under constant evaluation, and a future switch is a wish). After that choice, the best available package manager, most flexible way of package building, repository maintenance is pacman/makepkg for a rolling distro like KaOS. As for the Desktop Environment, there will never be a change, whether it is Linux or Illumos based, KDE Plasma will be the choice, Qt the Toolkit. With those choices in place, April 2013 package building for this independent distribution was started. KaOS is a build from scratch distribution, every package in every repository is build by and for KaOS. By July 2013 the initial goal of about 1500 packages was reached.
KaOS 2020.01 released.
First one is the addition of signed kernel modules for Linux 5.4. All internal modules are now automatically signed during the kernel build, out of tree modules like virtualbox-modules and NVIDIA packages have the signing added too.
Most notable major updates to the base of the system are LLVM/Clang 9.0.1, Glib2 2.62.4, Bison 3.4.2, Python3 3.7.6, Linux 5.4.7, Protobuf 3.11.1, Mesa 19.2.8, NetworkManager 1.22.2, Nano 4.7, GStreamer 1.16.2 and Qt 5.14.0
