My Custom Desktop Immutable Image  

Warning

Only use this image if you're curious and not afraid of breaking changes

This repo is part of a hobby project where I'm learning about bootable OCI images and CI/CD. My ultimate goal is to end up with the ideal base image for my laptop and maybe other devices.

Altough I'm currently daily driving the niri-nvidia image, and it's fully operational for my needs, I do not guarantee anything. I'd be happy you get in touch with me if you are using this image.

Image details

While multiple images are available through the Github Container Registry, those I'm currently maintaining are niri-nvidia and niri.

These images are built using Bluebuild template on top of Ublue OS's base-main image.

Highlights

• Based on the niri wayland compositor
• Automatic download of my dotfiles
• Shipped with tailscale
• Important softwares :
  • kitty
  • helix
  • rofi
  • ironbar
  • starship

Installation

Warning

This is an experimental feature, 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/benoitlx/niri: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/benoitlx/niri:latest
  

• Reboot again to complete the installation

  systemctl reboot
  

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

If build on Fedora Atomic, you can generate an offline ISO with the instructions available here. These ISOs cannot unfortunately be distributed on GitHub for free due to large sizes, so for public projects something else has to be used for hosting.

Verification

These images are signed with Sigstore's cosign. You can verify the signature by downloading the cosign.pub file from this repo and running the following command:

cosign verify --key cosign.pub ghcr.io/blue-build/template
