Usage

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

   rpm-ostree rebase -r ostree-unverified-registry:ghcr.io/aguslr/bluefusion:stable
   

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

   rpm-ostree rebase -r ostree-image-signed:docker://ghcr.io/aguslr/bluefusion:stable
   

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

sudo podman run --rm --privileged \
    --volume .:/build-container-installer/build \
    --security-opt label=disable --pull=newer \
    ghcr.io/jasonn3/build-container-installer:latest \
    IMAGE_REPO="ghcr.io/aguslr" \
    IMAGE_NAME="bluefusion" \
    IMAGE_TAG="latest" \
    VARIANT="Silverblue"
