Open Source Licenses

Linxira OS is built directly on Arch Linux and incorporates multiple upstream open source projects. Linxira OS is an independent project and is not affiliated with or endorsed by Arch Linux.

Linxira OS Own Licenses

Code & Configuration

Most Linxira OS code repositories (catalog, components, welcome, software and runtime setup, update tooling UI, crash watch, and the build repositories) are licensed under MIT. Repositories derived from, or containing, copyleft upstream code keep the upstream license: GPL-3.0-or-later (linxira-update, based on Arch-Update; linxira-hooks), GPL-3.0-only (linxira-hwd-detector, forked from CachyOS/chwd), and AGPL-3.0-or-later (linxira-bio-sdk). Each repository ships its own LICENSE file; where a repository modifies upstream code, an UPSTREAM.md records the upstream, the license, and the local changes.

Documentation & Website

Documentation, Wiki, and website content are licensed under CC BY-SA 4.0.

Brand Assets

Logos, wallpapers, icons, and other brand assets are reserved Linxira property and are not offered under a general public license. See the Brand Assets Policy.

Upstream Licenses

Each upstream component remains governed by its own license. Distribution together in Linxira OS does not place the entire operating-system aggregation under one license. Key upstream components include:

Component	Upstream Project	License
Base System	Arch Linux	Various component licenses
Desktop	KDE Plasma	GPL-2.0+
Planned Installer	Calamares	GPL-3.0+
Kernel	Linux Kernel	GPL-2.0
GNU Tools	GNU Project	GPL-2.0+ / LGPL-2.0+
Firefox	Mozilla	MPL-2.0
LibreOffice	The Document Foundation	MPL-2.0

GPL Copyleft Explanation

The GNU General Public License (GPL) applies to covered programs and derivative works of those programs. Merely aggregating GPL-licensed packages with separately licensed software in a distribution does not require every package or the distribution as a whole to use the GPL.

Impact on Linxira OS:

Linxira-owned code identified as GPL-3.0 is distributed under that license
Users running Linxira OS locally are not subject to copyleft restrictions
Users creating derivative distributions must comply with upstream licenses
User customizations and scripts are not subject to copyleft (unless they include GPL code)

Non-Free Components

Linxira OS may include the following non-free components:

Firmware: Some hardware requires proprietary firmware
GPU Drivers: NVIDIA drivers are proprietary
User-Optional: VS Code, Chrome, etc. are proprietary

These components are user-installed by choice; Linxira OS does not mandate non-free software.
