SimRacing Hub OS

A Linux distribution for sim racing — built on Bazzite.

Every major racing sim, SimHub, force-feedback hardware and a recording setup, working out of the box. No ads, no bloat, no tracking — the SimRacing Hub philosophy, as an operating system.

Status: early development — Phase 2, repository scaffold. The image builds, boots and identifies as SimRacing Hub OS. Sim racing software is layered in over the following phases.

What it is

• Base: Bazzite (GNOME) — Fedora atomic, gaming-tuned, with Steam, Proton and GE-Proton already on board.
• Two modes: a console-style Game Mode appliance and a full GNOME desktop, selectable at login — one machine, both jobs.
• Built in the cloud: every push is built by GitHub Actions and published as a container image. Installed systems then auto-update.

A note on iRacing

iRacing does not run on Linux — its anti-cheat is not enabled for Linux by iRacing, and no distribution can change that. iRacing users should keep a small Windows dual-boot for it. Every other major sim — ACC, Assetto Corsa, Automobilista 2, rFactor 2, Le Mans Ultimate, F1 — runs well through Proton.

Live status is tracked at areweanticheatyet.com.

Install

See docs/install.md for the full guide. In short, on an existing Bazzite system:

sudo bootc switch ghcr.io/halvar20000/simracinghub-os:latest

A standalone installable ISO is produced in a later phase.

How it is built

Path	Purpose
Containerfile	Defines the image — starts from Bazzite, layers our changes
build_files/build.sh	Build-time package installs and system tweaks
system_files/	Files overlaid onto the OS (config, branding, udev rules)
scripts/	Helper scripts shipped into the OS (e.g. SimHub setup)
.github/workflows/build.yml	GitHub Actions: build & publish the image
docs/	Install guide and the tested-hardware matrix
branding/	Source assets — logo, boot splash, wallpapers

Roadmap

Phase	Work	Status
1	Design & build plan	Done
2	Repository scaffold	Current
3	Sim racing packages & gaming tweaks	Planned
4	SimHub first-run helper	Planned
5	FFB drivers, telemetry & hardware support	Planned
6	Branding — splash, wallpapers, OBS preset	Planned
7	CI publish to ghcr.io + installable ISO	Planned
8	Hardware testing & user documentation	Planned
