I've just filed
    https://salsa.debian.org/lucas/collab-qa-tools/-/merge_requests/12
with a script that, as I expect, should be enough to run this test.


It's similar in spirit on how vagrant run the last test rebuild,
`sed`ing a "live" file instead of providing a patched package, as I
understand that's a good enough way to do it.
