So we have the RedHatQE tests, Taskotron and CentOS's CI. Can anyone
of the people involved (at the Red Hat side, I guess) well me why we
have 3 systems for 1 task? When I took ownership of this "external
need" (for the Fedora cloud product) I was under the impression we
only just (are going to) have Taskotron and everyone knows it's THE
way to go.
