I think the OpenShift example is a good example of a class of problems. If I thought we'd never hit this problem again if we just changed that OpenShift code then I would go that route instead of this route. > I would be happy to withdraw this Change if we had solutions to these > problems, because from a Fedora Cloud perspective, we basically nearly > never hit the fallback case except for Vagrant (where it makes sense > to have it trigger).

If we could make changes to make it more likely that a user will set a hostname properly then that is great and they won't hit the fallback case. _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
