Installation

Here is the recommened installation process.

• Flash the Zirconium ISO from the project's GitHub onto a USB.
• Boot from the USB and install Zirconium.
• Boot into Zirconium.

Tip

This process should work from any Fedora-based bootc image.

• Once in a bootc system, switch to this image.

# Normal image
sudo bootc switch ghcr.io/cvsickle/zirconium:latest
# Nvidia image
sudo bootc switch ghcr.io/cvsickle/zirconium-nvidia:latest

# Reboot when done.
systemctl reboot

• Once booted into this image, enable signing verification.

# Normal image
sudo bootc switch --enforce-container-sigpolicy ghcr.io/cvsickle/zirconium:latest
# Nvidia image
sudo bootc switch --enforce-container-sigpolicy ghcr.io/cvsickle/zirconium-nvidia:latest

• If the boot loader menu entries are still showing the upstream image name, force them to update.

sudo rpm-ostree kargs --append=bls.refresh=1
systemctl reboot

sudo rpm-ostree kargs --delete=bls.refresh=1
systemctl reboot

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/cvsickle/zirconium
