I tried Kinoite a while back and the included Box Buddy couldn't clone containers. I took it all the way back to the docker command that was cloning and it would just fail out. Same version of Box Buddy/Distrobox/docker on regular Fedora worked fine. Pinged the developer of Box Buddy and he figured it was something about how Kinoite worked that was messing with it and I should ask the Kinoite maintainers. At that point my curiosity was exhausted and I'd run into the software install annoyances with rpm-ostree based distros, and just went back to Fedora.
