Introduction

HeliumOS has charted a remarkable journey from its CentOS Stream roots to become a pioneering immutable Linux distribution focused on reliability and long-term support. Inspired by the CentOS spiritual successor AlmaLinux and designed for atomic updates, HeliumOS merges enterprise-grade stability with modern containerised workflows. Over successive milestones—alpha, beta and now the full HeliumOS 10 release—this project has showcased unique features such as bootable containers, robust rollback mechanisms and a ten-year support promise, all wrapped in a user-friendly desktop environment. This article explores the historic milestones, distinctive capabilities and practical steps for adopting HeliumOS 10, whether at home or within an enterprise setting.

Historical Milestones and Unique Features

HeliumOS first emerged as a proof of concept that combined CentOS Stream’s reliability with atomic, image-based updates. Early development relied on Bash scripts to assemble bootable container images, a method termed bootc, which packages the kernel, libraries and dependencies into a unified container. This approach laid the groundwork for seamless system updates and rapid, system-wide rollback in case of failures.

Following its initial success, the project transitioned base sources from CentOS Stream to AlmaLinux 9, resulting in HeliumOS 9. By adopting AlmaLinux’s enterprise-oriented kernel and a commitment to a decade of maintenance, the developers ensured a stable foundation measured in years rather than months. Alongside immutable updates, HeliumOS introduced KDE Plasma as its default desktop, catering to both visual polish and performance.

Unique aspects of HeliumOS include:

  • Bootable Containers (bootc): Encapsulate the entire operating system in self-contained images, minimising dependency conflicts and simplifying updates.

  • Atomic Updates: Each update applies holistically; if a patch fails, the system can revert to a known good state instantly.

  • Long-Term Support: Leveraging AlmaLinux’s ten-year lifecycle, HeliumOS guarantees security fixes and patches over an extended timeframe.

  • Security-First Design: Secure Boot support, default Btrfs filesystem with optional LUKS encryption and a signed kernel ensure system integrity from first boot.

  • Developer-Friendly Toolchain: Shift from handcrafted scripts to Ansible YAML and Podman for reproducible builds, reflecting a mature DevOps ethos.

These design choices blend innovation with conservatism, prioritising reliability without stifling modern Linux experiences.

What’s New in HeliumOS 10

The full HeliumOS 10 release, officially declared on 28 July 2025, marks a significant leap from its predecessor despite the numbering oddity—HeliumOS 9 was already based on AlmaLinux 9. Version 10 builds atop AlmaLinux 10, integrating Linux kernel 6.12, which introduces enhanced hardware support, performance improvements and security hardening for enterprise workloads.

Key enhancements in HeliumOS 10 include:

  • Kernel 6.12 with Secure Boot: Signed LTS kernel for stronger assurance in UEFI environments.

  • Zsh as Default Shell: Power users benefit from an advanced scripting shell, pre-configured with a clean, minimal prompt.

  • Btrfs Filesystem by Default: Snapshot capabilities for instant rollbacks, plus built-in checksums and optional full-disk encryption via LUKS.

  • Preinstalled Docker: Container runtime available out of the box, streamlining deployment of microservices and development sandboxes.

  • Transition to Ansible-Driven Builds: Replaces legacy Bash tooling, ensuring consistent, auditable build pipelines managed through Podman-based containers.

  • Edge Edition (Experimental): Offers a newer kernel branch for cutting-edge hardware enablement, useful for test environments and early adopters.

  • NVIDIA Open Kernel Modules Support: Smooth integration for GPU-accelerated workloads, from scientific computing to creative applications.

  • Critical Bug Fixes: Addresses stuttering on Nvidia GPUs and a systemd service conflict causing panics, solidifying stability.

This collection of updates demonstrates HeliumOS’s continued focus on marrying immutable infrastructure with enterprise reliability, while enhancing the developer and end-user experience.

Getting, Installing and Using HeliumOS

Whether you’re exploring a home lab setup or standardising desktops across an organisation, HeliumOS 10 offers multiple installation pathways. Pre-built ISO images are available for direct installation, while container enthusiasts can deploy HeliumOS in virtual machines or on bare metal.

To obtain and install HeliumOS 10:

  1. Visit the official HeliumOS download page and select the appropriate ISO for your architecture.

  2. Verify the ISO signature using the provided public key to ensure file integrity.

  3. Create a bootable USB or mount the ISO in your virtualisation platform.

  4. During installation, choose Btrfs and enable LUKS if full-disk encryption is required.

  5. Complete the guided setup for user accounts and network configuration.

  6. Reboot into the new HeliumOS environment, assured by Secure Boot validation.

Once installed, first-time users encounter the polished KDE Plasma desktop. To harness HeliumOS’s atomic nature:

  • Use the bootc command-line tool to manage container images and switch between system snapshots.

  • Invoke sudo rpm-ostree upgrade (part of the rpm-ostree system, a hybrid image/package management tool used primarily in Fedora-based operating systems like Fedora Silverblue, CoreOS, and Fedora IoT.) to fetch and apply atomic updates, with automatic snapshot rollbacks on failure.

'sudo rpm-ostree upgrade' (zsh - Konsole)

  • Leverage the integrated Docker environment: run docker pull and docker run commands without additional setup.

Home users appreciate the simplicity of atomic upgrades and the safety net of snapshots before every system change. Enterprises benefit from automated provisioning scripts—using Ansible playbooks provided in HeliumOS’s Git repository—to replicate identical desktop images across multiple endpoints, minimising drift and administrative overhead.

Support and Troubleshooting

HeliumOS’s single-developer origin has prompted calls for a broader community, yet robust support channels are already forming:

  • Community Forum and Chat: Active discussion on Reddit’s r/linux and dedicated Matrix channels offers peer-to-peer troubleshooting.

  • Issue Tracker: Report bugs or feature requests on the project’s GitHub repository; contributions are welcome under the open-source licence.

  • Enterprise SLA Options: Consulting firms specialising in AlmaLinux can extend support contracts to HeliumOS deployments, ensuring SLA-driven response times.

Common troubleshooting steps include:

  • Inspecting Btrfs snapshots (sudo btrfs subvolume list /) to confirm system rollbacks.

  • Reviewing kernel log entries (journalctl -k) for hardware drivers or Secure Boot conflicts.

  • Validating Docker network configuration if containerised services fail to communicate.

  • Switching to the Edge Edition kernel for improved hardware compatibility, especially on newer GPUs.

By blending official resources with community wisdom, users can resolve most technical hurdles while maintaining confidence in their immutable infrastructure.

Future Plans

Looking ahead, the HeliumOS roadmap hints at:

  • Multi-Developer Collaboration: Onboarding additional maintainers to diversify expertise and accelerate feature development.

  • Expanded Architecture Support: Adding ARM64 and RISC-V images to cater to single-board computers and emerging platforms.
