@vrutkovs I guess most jobs will not pass as openshift-tests will fail, did you tested it works locally ?

[vrutkovs]

did you tested it works locally

No, I don't have the hardware for this. My plan is:

• ensure e2e tests pass on rhel8
• run test with rhel9 via cluster bot to find rhel9-specific issues

[danmanor]

@vrutkovs I will try as well with RHEL9
