Thanks, the patch looks mostly good to me but I am not convinced of
keeping the tests across versions in this form. I don't think they are
tested in BF, only one can manually create a setup to test. Shall we
remove it for now and then consider it separately?

Apart from that, I have made minor modifications in the docs to adjust
the order of various prerequisites.
