Legacy template

Warning
This repository was previously ublue-os/startingpoint, but has now been moved to the BlueBuild organization. New custom images should be created from the new blue-build/template, but this repository will be supported for the foreseeable future.
Check out the migration guide for migration instructions.

Installation

Warning
This is an experimental feature, try at your own discretion.

To rebase an existing Silverblue/Kinoite 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/blue-build/legacy-template: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/blue-build/legacy-template: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

This template includes a simple Github Action to build and release an ISO of your image.

To run the action, simply edit the boot_menu.yml by changing all the references to startingpoint to your repository. This should trigger the action automatically.

The Action currently uses ublue-os/isogenerator-old and works in a similar manner to the official Universal Blue ISO. If you have any issues, you should first check the documentation page on installation. The ISO is a netinstaller and should always pull the latest version of your image.

Note that this release-iso action is not a replacement for a full-blown release automation like release-please.

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/legacy-template
