Cyberus Technology Resilient Linux is a commercially supported downstream distribution of NixOS focused on Embedded Devices.
On top of NixOS' key features, reproducibility and the declarative module system, CTRL-OS offers long-term support for 5 years and is ready for the Cyber Resilience Act (CRA). If you're using NixOS 24.05, it is a drop in replacement.
If you are unsure where to start with CTRL-OS, check out the documentation.
While you can freely use CTRL-OS and get access to all sources as part of the channel tarball, we are not quite ready for a release on GitHub yet. We plan to do so in the near future.
Meanwhile feel free to use the issue tracker.
Please have a look at our documentation for the current roadmap.
