I have created my own image using https://workshop.blue-build.org/ that is now located at GitHub - CeruleanDerpo/kinoite-niri-nvidia
I have followed the instructions on the README but it only let me rebase to the unsigned image, while trying to rebase to the signed image gives me this output:
$ rpm-ostree rebase ostree-image-signed:docker://ghcr.io/ceruleanderpo/kinoite-niri-nvidia:latest
