Can you verify that this would be set in the vms? I belivenit was missing on those configs.

So some VMs don’t generate their config with the perl script. I just want to make sure these have it set correctly (it may be in the profile but i can’t remember).

Ok sounds good as a warning. Look out for issues regarding this though. I think the fixes should be easy it’s just generated somewhere I can’t find now

The intent is that without stateVersion, you get the behaviour of the latest release, which presumably is not broken.

When doing release upgrades with nixos-rebuild, it is untrue that you get unbroken behavior without stateVersion.

To make warning more justified, we can do like this:

1. Each module exports whether it depends on system.nixos.stateVersion

system.nixos.dependsOnStateVersion = mkIf_isNotOverriden cfg.package [ "services.postgresql.enable" ];

(I don't think we can check whether cfg.package evaluation depends on system.nixos.stateVersion, but if it is overriden in user configuration, then user probably pins it to some concrete version, so he doesn't require setting system.nixos.stateVersion)
2. Here we check if system.nixos.dependsOnStateVersion is empty. If it is, then no warning - user is aware of all his stateful options or doesn't have stateful options enabled. Otherwise we display list of options that would case disruption on release upgrades and abort evaluation.
