Hey, I recall they have installation smoke tests using rocky8 within k3s repo (ref).
However, I don’t know if there are any known issues for said distro.
Sorry, by “smoke tests” I meant minimal test that verifies a specific behavior. In this case, we can see they verify often the installation process on Rocky 8 which includes:
• Installing a single node cluster
• List available nodes
• List running pods
• Verify running system components
Regarding, being officially supported I don’t know, I only found this on the documentation (which I don’t think it is what you are looking for).
