# Manifests for rpm-ostree based Fedora variants
This is the configuration needed to create
[rpm-ostree](https://coreos.github.io/rpm-ostree/) based variants of Fedora.
Each variant is described in a YAML
[treefile](https://coreos.github.io/rpm-ostree/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](https://pagure.io/pungi-fedora) with
[Lorax](https://github.com/weldr/lorax)
([templates](https://pagure.io/fedora-lorax-templates)).
## Fedora Silverblue
- Website: https://silverblue.fedoraproject.org/ ([sources](https://github.com/fedora-silverblue/silverblue-site))
- Documentation: https://docs.fedoraproject.org/en-US/fedora-silverblue/ ([sources](https://github.com/fedora-silverblue/silverblue-docs))
- Issue tracker: https://github.com/fedora-silverblue/issue-tracker/issues
## Fedora Kinoite
- Website: https://kinoite.fedoraproject.org/ ([sources](https://pagure.io/fedora-kde/kinoite-site))
- Documentation: https://docs.fedoraproject.org/en-US/fedora-kinoite/ ([sources](https://pagure.io/fedora-kde/kinoite-docs))
- Issue tracker: https://pagure.io/fedora-kde/SIG/issues
## Building
Instructions to perform a local build of Silverblue:
```
# Clone the config
git clone https://pagure.io/workstation-ostree-config && cd workstation-ostree-config
# Prepare directories
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
```
## Testing
Instructions to test the resulting build:
- First, serve the ostree repo using an HTTP server. You can use any static file server. For example using <https://github.com/TheWaWaR/simple-http-server>:
```
simple-http-server --index --ip 192.168.122.1 --port 8000
```
- Then, on an already installed Silverblue system:
```
# Add an ostree remote
sudo ostree remote add testremote http://192.168.122.1:8000/repo --no-gpg-verify
# 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/rawhide/x86_64/silverblue
# Reboot and test!
```
## Branching instructions for new Fedora releases
Follow those steps during the Fedora branch process in Fedora:
### Fedora Ansible
Make a PR similar to
[ansible#1318](https://pagure.io/fedora-infra/ansible/pull-request/1318) in
[fedora-infra/ansible](https://pagure.io/fedora-infra/ansible).
### On Rawhide / main branch
```
sed -i "s/40/41/g" *.repo *.yaml comps-sync.py
mv fedora-40.repo fedora-41.repo
mv fedora-40-updates.repo fedora-41-updates.repo
sed -i "s/41/42/g" README.md
sed -i "s/40/41/g" README.md
```
### On the new branch (f40)
```
rm fedora-rawhide.repo
sed -i "/- fedora-rawhide/d" *.yaml
sed -i "/# - fedora-40/- fedora-40/" *.yaml
```
