Saw recently on Twitter that Github is now allowing you to set up third-party external autolinks. So, just like when you type “#2048” on Github it creates a link to Github issue #2048, we could set it up in Foreman and Katello so that it could do the same for Redmine when you type “RM-28041” for example. I think this would be useful to have in our repos
