@cgwalters @henrywang Sorry, do you guys think you'd be able to help me figure out how to stop the integration tests from skipping?

Hi! I think we can reuse image-install-upgrade.sh and check-system.yaml.

I forgot to mention here that I added kargs tests in b777459 (that said, it makes sense to have some in the e2e tests too)
