During deploy, I get
trace: warning: system.stateVersion is not set, defaulting to 22.05. Read why this matters on https://nixos.org/manual/nixos/stable/options.html#opt-system.stateVersion.
But it is set in my configuration (as reported trace that stateVersion is not set, but it is? · Issue #191622 · NixOS/nixpkgs · GitHub). I want to re-submit this here because nobody reacted on the issue yet and I don’t know whether this is actually a real issue or whether I can ignore it.
