Thanks! Ideally we'd actually test this before merging, but in the past it's been quite safe. When merging this (and other PRs like this one that update a service), watch the rebuild and deployment in OpenShift to sanity-check it comes up fine.

Will keep that in mind, thanks for the review!

I found this on Openshift (no errors were recorded):

STEP 7/7: LABEL
...
 "io.openshift.build.commit.message"="Merge pull request #186 from c4rt0/moveToFedora39"
  "io.openshift.build.commit.ref"="main" "io.openshift.build.name"="config-bot-39"  

I guess that's safe.

Yeah, that's the image build. You'll want to also check that the new pod comes up and is happy (oc get pods).

Also, this would happen after that PR is merged. Those logs are from when #186 was merged it looks like. (But a good time to also check that the importer is also up and running fine.)
