## About
Miasma OS is a [Fedora Atomic desktop](https://fedoraproject.org/atomic-desktops/) built with love on top of a Bazzite base. It is a spin aimed at music producers and musicians utilising features found in [Fedora Jam Lab](https://fedoraproject.org/labs/jam/), [Av Linux](https://www.bandshed.net/avlinux/) and [Ubuntu Studio](https://ubuntustudio.org/) but on an immutable base thanks to [Bazzite](https://bazzite.gg/) and [Universal blue](https://universal-blue.org/).

## Installation

> [!WARNING]  
> [This is an experimental feature](https://www.fedoraproject.org/wiki/Changes/OstreeNativeContainerStable), try at your own discretion.

To rebase an existing atomic Fedora installation to the latest build:

- First rebase to the unsigned image, to get the proper signing keys and policies installed:

  ```
  rpm-ostree rebase ostree-unverified-registry:ghcr.io/tumillanino/miasma-os:latest
  ```

- Reboot to complete the rebase:

  ```
  systemctl reboot
  ```

- Then rebase to the signed image, like so:

  ```
  rpm-ostree rebase ostree-image-signed:docker://ghcr.io/tumillanino/miasma-os:latest
  ```

- Reboot again to complete the installation

  ```
  systemctl reboot
  ```

- On first launch, please open Alacritty and run the script below in order to properly configure Wine with Yabridge, Reaper paths, and system flags.

```
  ujust first-run
```

The `latest` tag will automatically point to the latest build. That build will still always use the Fedora version specified in `recipe.yml`, so you won't get accidentally updated to the next major version.

## ISO

An ISO and website is coming soon ...

## Verification

These images are signed with [Sigstore](https://www.sigstore.dev/)'s [cosign](https://github.com/sigstore/cosign). You can verify the signature by downloading the `cosign.pub` file from this repo and running the following command:

```bash
cosign verify --key cosign.pub ghcr.io/tumillanino/miasma-os
```
