One test actually fails. No idea why, potentially related to us using the system MIT krb5? I've seen some mentions that it's not fully up to par with heimdal yet.

I also didn't manage to run ctdbd so I hope the new "stop" script works. :) It is how upstream does it in their .service file but I think systemd always falls back to just KILLing the service after a bit if the more gentle methods don't succeed which I don't think runit automatically does.
