Another issue I came across was the fact that different sources provided different "requirements". For example, some sources stated that when creating the kojihub and kojiweb certs that the "Common Name" value is required to be a FQDN (Fully Qualified Domain Name) while others said it didnt. This made troubleshooting the kojihub process rather strenuous.
