A minimal Fedora ostree base image
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:
sudo rpm-ostree rebase ostree-unverified-registry:ghcr.io/ublue-os/startingpoint:latest
- Reboot to complete the rebase:
systemctl reboot
- Then rebase to the signed image, like so:
sudo rpm-ostree rebase ostree-image-signed:docker://ghcr.io/ublue-os/startingpoint:latest
- Reboot again to complete the installation
systemctl reboot
This repository builds date tags as well, so if you want to rebase to a particular day's build:
sudo rpm-ostree rebase ostree-image-signed:docker://ghcr.io/ublue-os/startingpoint:20230403
This repository by default also supports signing.
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.
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 uses isogenerator 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.
The just
command runner is included in all ublue-os/main
-derived images.
You need to have a ~/.justfile
with the following contents and just
aliased to just --unstable
(default in posix-compatible shells on ublue) to get started with just locally.
!include /usr/share/ublue-os/just/main.just
!include /usr/share/ublue-os/just/nvidia.just
!include /usr/share/ublue-os/just/custom.just
Then type just
to list the just recipes available.
The file /usr/share/ublue-os/just/custom.just
is intended for the custom just commands (recipes) you wish to include in your image. By default, it includes the justfiles from ublue-os/bling
, if you wish to disable that, you need to just remove the line that includes bling.just.
See the just-page in the Universal Blue documentation for more information.
