After https://github.com/openshift/installer/pull/3429 the metal compact job no longer works.
We can see that this fixed e2e-metal compact variant here https://testgrid.k8s.io/redhat-openshift-ocp-release-4.5-informing#release-openshift-ocp-installer-e2e-metal-compact-4.5 There's still e2e test failures but at least it's successfully installing now.
Verified: with test grid at https://testgrid.k8s.io/redhat-openshift-ocp-release-4.5-informing#release-openshift-ocp-installer-e2e-metal-compact-4.5 As Scott said, the e2e-metal compact installation now works again. This is sufficient for the verification.
