Rebase to a different Fedora atomic distro
ostree remote refs fedora
sudo rpm-ostree rebase fedora:fedora/35/x86_64/kinoite
sudo rpm-ostree rebase ostree-unverified-registry:ghcr.io/winblues/vauxite:latest
Reboot.
Rebase to the signed image (if it exists):
sudo rpm-ostree rebase ostree-image-signed:docker://ghcr.io/winblues/vauxite:latest
Reboot.
(Optional) Create a new user account. (I don't actually know how important this step is, but it's recommended in the winblues Blue95 docs.)
