BlueFusion

A Fedora Silverblue image that adds RPM Fusion with media codecs and replaces Toolbox with Distrobox.

Usage

1. Rebase to an unsigned image to get proper signing keys:

   rpm-ostree rebase ostree-unverified-registry:ghcr.io/aguslr/bluefusion:latest && systemctl reboot
   

2. Rebase to a signed image to finish the installation:

   rpm-ostree rebase ostree-image-signed:docker://ghcr.io/aguslr/bluefusion:latest && systemctl reboot
   

Alternatively, an ISO file for offline installation can be generated with the following command:

sudo podman run --rm --privileged --volume .:/isogenerator/output \
    --security-opt label=disable --pull=newer \
    -e IMAGE_REPO="ghcr.io/aguslr" -e IMAGE_NAME="bluefusion" \
    -e IMAGE_TAG="latest" -e VARIANT="Silverblue" \
    ghcr.io/ublue-os/isogenerator:39

Features

• Start with a custom Fedora Silverblue image.
• Replace toolbox with distrobox.

Verification

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