This should be a new section to the E2E startup test, not an entirely new test. If this coverage only concerns server, it should just be an integration test.

Really good point. We can verify this by just using one server, so it could be an integration test. I need to learn how to create one though (sorry, I'm probably going to continue bugging you 🤦 )

Please add this test to the integration matrix, so it can run in CI. https:/k3s-io/k3s/blob/master/.github/workflows/integration.yaml#L41
