The `system.stateVersion` option is not defined in your
nix-darwin configuration. The value is used to conditionalize
backwards‐incompatible changes in default settings. You should
usually set this once when installing nix-darwin on a new system
and then never change it (at least without reading all the relevant
entries in the changelog using `darwin-rebuild changelog`).
You can use the current value for new installations as follows:
system.stateVersion = ${toString config.system.maxStateVersion};
'';
}
];
};
}
