Fedora Silverblue with Project Nobara gaming enhancements.
I do not provide any ostree remote for this project or any support. Use at your own risks.

A github CI updates the docker once changes are made in the repository. The docker generate a fresh remote every 3 hours. Nginx or Apache are required to host the repository.
The docker only requires a volume on /repo.
Once your repo is self-hosted add it on Silverblue and rebase:

sudo ostree remote add --no-gpg-verify remote-name https://your-domain.local/ostree
sudo rpm-ostree rebase remote-name:fedora/36/x86_64/silvernobora

• martinpitt on github for the inspiration
• gloriouseggroll for all the time and effort that goes through Nobara and ProtonGE.

This is the configuration needed to create rpm-ostree based variants of Fedora. Each variant is described in a YAML treefile which is then used by rpm-ostree to compose an ostree commit with the package requested.

In the Fedora infrastructure, this happens via pungi with Lorax (templates).

Instructions to perform a local build of Silverblue:

# Clone the config
git clone https://pagure.io/workstation-ostree-config && cd workstation-ostree-config

# Prepare repo & cache
mkdir -p repo cache && ostree --repo=repo init --mode=archive

# Build (compose) the variant of your choice
sudo rpm-ostree compose tree --repo=repo --cachedir=cache fedora-silverblue.yaml

# Update summary file
ostree summary --repo=repo --update

Instructions to test the resulting build:

• First, serve the ostree repo using an HTTP server.
• Then, on an already installed Silverblue system:

# Add an ostree remote
sudo ostree remote add testremote http://<IP_ADDRESS>/repo

# Pin the currently deployed (and probably working) version
sudo ostree admin pin 0

# List refs from variant remote
sudo ostree remote refs testremote

# Switch to your variant
sudo rpm-ostree rebase testremote:fedora/35/x86_64/silverblue
