AerynOS 2025.08: A Confident Stride Forward

Closing out August 2025, the AerynOS team has delivered its third release of the year — a milestone that reflects both technical ambition and a sharpened focus on the project’s long-term scalability. This update is not just a collection of package bumps; it’s a carefully orchestrated step towards a more structured, reproducible, and developer-friendly Linux distribution.

The development cycle leading to 2025.08 was marked by a deliberate re-evaluation of priorities. The team’s guiding principle has been to “deliver core Linux distribution tooling that will simplify our ability to scale out over time.” This has meant refining installation workflows, introducing foundational technologies like package sets, expanding hardware and virtualisation support, and continuing to polish the user experience — all while keeping the alpha status in mind.

Key Distribution Updates

The AerynOS repository has seen a wave of significant updates, ensuring that users and contributors have access to modern, high-performance software stacks. Highlights include GNOME 48.4, KDE Plasma 6.4.4, Sway 1.11, Cosmic Alpha 7, Linux kernel 6.15.11, Mesa 25.2.1, LLVM 20.1.8, and ffmpeg 7.1.1. New additions such as Waydroid 1.5.4, openvpn 2.6.14, protontricks 1.13.0, and winetricks 20250102 broaden the system’s versatility.

A subtle but impactful fix to PATH configuration has made console logins fully stateless, while enabling sulogin provides a single-user root shell for diagnosing and repairing boot failures. These refinements, though not headline-grabbing, are crucial for system reliability and maintainability.

Package Sets: The First Step Towards System Models

One of the most important architectural changes in 2025.08 is the introduction of package sets — curated collections of packages grouped for a specific purpose, such as a base system or a particular desktop environment. Each DE in AerynOS now has an associated “recommended” package set, with optional “minimal” or “full” variants depending on user needs.

This is more than a convenience feature; it’s a stepping stone towards the future “system-model” capability, which will allow exact reproduction of a user’s installed system. For now, package sets consolidate installation choices and lay the groundwork for more advanced system management.

Lichen: Smarter, More Guided Installs

The lichen network installer has been adapted to work seamlessly with package sets. During installation, users are guided through a TUI to select their preferred DE, with moss resolving dependencies based on the chosen set. Because lichen pulls the latest packages from the repository, installations are always up to date without requiring a post-install update step.

Usability has improved with prompts that check for an active internet connection and remind users to pre-format their disk — a deliberate “anti-usability” measure in the alpha stage to deter beginners and reduce support overhead. This will change in the future, but for now, the focus remains on attracting technically capable testers and contributors.

Virtualisation and Hardware Enablement

AerynOS 2025.08 strengthens its position as a development-friendly platform by improving both host and guest virtual machine support. On the host side, virt-manager is now in the repository, enabling efficient testing of package sets and system changes. As a guest, AerynOS benefits from expanded kernel hardware support, including Hyper-V enablement based on user requests.

These enhancements make it easier for contributors to experiment without risking production systems, while also broadening the range of environments in which AerynOS can run.

Scheduling for Responsiveness

The repository now includes scx-scheds, with scx_flash set as the default scheduler for new installs. This scheduler prioritises fairness and predictable performance, ensuring that systems remain responsive even under heavy workloads like package building. Existing installs can opt in by manually installing scx-scheds.

Desktop Environment Evolution

KDE Plasma 6.4.4 is now officially supported and installable from ISOs, fulfilling one of the community’s most frequent requests. Cosmic DE, at Alpha 7, is moving to a bi-weekly update cycle to keep pace with upstream development, while Sway 1.11 has been refined with Waybar and other enhancements for a better tiling experience.

A console-only installation option has also been introduced for advanced users who want to build their environment from the ground up. GNOME remains the default live environment, updated to 48.4 and running smoothly without major intervention.

Tooling Enhancements

Two new moss commands expand system management capabilities:

moss state diff – Compares two system states, showing differences in package versions and installed/removed packages.
moss search-file – Identifies which package owns a given file under /usr.

These tools improve transparency and control, especially for developers and testers working with multiple system states.

Ongoing Work and Documentation

The team is progressing on integrating moss with PackageKit and generating AppStream metadata for DE software centres like GNOME Software, KDE Discover, and Cosmic Store. This will make graphical package management possible, though command-line familiarity remains recommended.

Documentation is also receiving sustained attention, with improvements to FAQs, update guides, DE overviews, and philosophical background. Future work will focus on contribution guides and packaging tutorials, addressing feedback about fragmented or missing documentation.

Looking Ahead

The roadmap for the rest of the year includes implementing versioned repositories — a prerequisite for delivering new OS tooling features seamlessly — and enhancing moss and boulder with structured logging, better error handling, and JSON output for structured data parsing.

Conclusion

AerynOS 2025.08 is a confident, technically rich release that balances innovation with careful pacing. By introducing package sets, refining installation workflows, expanding hardware and VM support, and enhancing tooling, the project is laying a strong foundation for its future system-model vision. While still firmly in alpha, this release demonstrates that AerynOS is not just evolving — it’s maturing with intent.
