AerynOS

Overview

AerynOS is a free, open-source Linux distribution based on independently built source code, using a rolling release model. Designed with simplicity, performance, and reliability as core principles, it aims to remove the technical burdens of traditional Linux and provide users with a highly efficient operating system platform. Maintained by a team of Irish developers (the project has its roots in Ireland), it is hosted at aerynos.com and GitHub. It supports the x86_64 architecture (arm64 is currently being tested) and is suitable for desktop, server, and cloud environments, offering desktop environments such as GNOME and KDE Plasma. AerynOS uses a custom package manager, supports containerization and atomic updates, and emphasizes "OS as Infrastructure," making it suitable for developers and system administrators. AerynOS is a renamed version of Serpent OS (renamed in March 2025), born out of dissatisfaction with Serpent OS and a refocused effort.

History and Development

• Origin:
  • 2024: The AerynOS project was launched by a team of Irish developers as a renamed version of Serpent OS, aiming to redefine the operating system, eliminate the historical burdens of Linux, and provide atomic updates and an efficient platform.
  • Serpent OS (predecessor) was launched in 2022 by Ikey Doherty, but was renamed AerynOS in March 2025 due to community issues.
• Development History:
  • 2024: Early versions were based on the Serpent OS code and provided basic desktop support.
  • March 29, 2025: AerynOS 2025.03 was released, introducing atomic updates and an efficient toolchain.
  • 2025: The project remains active on GitHub, with community-developed documentation, but no major new releases have been released.
• Community and Support:
  • Maintained by an Irish team, hosted on aerynos.com, GitHub, and aerynos.dev.
  • Supports English and some Chinese (depending on the desktop environment). Documentation includes installation guides and development manuals.
  • A Reddit user called AerynOS "the new Serpent OS: simple and powerful."
• Open Source License:
  • GPL v3 (core scripts), MIT (some tools).

Key Features

AerynOS is built around atomic updates, performance, and simplicity, perfect for desktop users. Here are its key features:

   • Atomic updates ensure safe system upgrades and support rollbacks.
3. Independent Source Code
   • Built from source code, supports musl libc and the LLVM toolchain.
4. Performance Optimization
   • Removes technical burden and provides an efficient kernel.
   • Requires approximately 1-2 GB of RAM and supports Wayland.
5. Security and Privacy
   • Supports the ufw firewall and ZFS.
6. Development Support
   • Supports Python, Node.js, and other packages, installed via a custom package manager.

Advantages and Limitations

Advantages
