Seems like we have another (random?) test failure:

Just noting here that the runuser command might be better than sudo for our use case here (we always run the test scripts as root by default), thanks @pmatilai for the hint 😄

So this only happens on Ubuntu 24.04 which GH has been slowly updating its runners to. Don't know yet whether this is a bug in the image itself or something that our particular setup is causing. We've locked the test-suite on 22.04 now so this is very much non-urgent matter.

Fixed by 7b1eefb by avoiding the use of sudo in the first place.
