I get the idea of "this is autoconfiguring", but I don't like it. The
only way you can see what tests ran is by looking at the output. Well,
OK, that might be well and good, but it means you have to look at
Jenkins and poke around. It means you can't easily exclude a package
of tests that simply can't have its tests run today, but we don't want
to remove the package from the base image. (Also, I like
