AerynOS Feb 2026 Snapshot Updates Desktops, MOSS Gets Faster

The in-development Linux distribution AerynOS has released its February 2026 progress report together with a new test image, AerynOS 2026.02 Alpha. The build ships with the long-term-support Linux 6.18 kernel and continues the project’s focus on atomic update technology rather than strict immutability.

Like earlier releases, the ISO boots into a live GNOME session that mainly acts as a launcher for the project’s Lichen installer. Because the installer pulls the newest package sets during deployment, an internet connection is required to complete installation.

Performance work on the distribution’s MOSS update system has produced notable gains. Developers report that on modern SSD or NVMe storage, a cold atomic transaction touching roughly 65,000 files can now complete in about a second, significantly improving update responsiveness.

The new ISO also introduces two lightweight installation paths. The long-standing Headless option remains intended for server deployments using wired networking, while the updated Console-only mode now includes wireless support so systems depending on Wi-Fi remain usable immediately after setup.

On the desktop side, the February snapshot bundles refreshed environments, including
COSMIC
updated GNOME builds
and the latest releases of KDE Plasma and its associated components. Improvements across these environments include stability fixes, usability refinements, accessibility enhancements, and new first-run configuration features.

Beyond the graphical stack, a broad set of core packages has been refreshed, with updates landing across graphics drivers, virtualization tools, multimedia components, and major applications such as Docker, QEMU, and Firefox.

The project’s package build utility, Boulder, has also received meaningful changes. Version values in recipes are now treated as strings automatically, upstream sources can be cached to reduce redundant downloads, and a new verification switch helps maintainers compare rebuilt manifests with repository versions to detect outdated artifacts.

Meanwhile, work has wrapped up on the design of a next-generation repository structure for MOSS. To support this transition, the team has temporarily paused the addition of new packages while focusing on stability and tooling improvements.

The AerynOS 2026.02 Alpha image is available for testing on the project’s download page. It is intended strictly for evaluation, not production use. Installation remains entirely terminal-based through the Rust-built Lichen installer, meaning users must prepare disk partitions manually before deployment.

Alongside the updated ISO, the project team also shared a detailed overview of their accomplishments in February, as outlined in the announcement.
