without these changes the tests will very repeatably (although not very reliably) wedge in our runs. the ssh command starts, opens a sessions, does something, the session closes again, but the test does not move on. adding *just* the redirect and not the unit waits is not sufficient either, it needs both. this feels like a bug in the nixos testing framework somewhere, but digging that far is not in the cards right now.
