This value determines the NixOS release from which the default
settings for stateful data, like file locations and database versions
on your system were taken. It‘s perfectly fine and recommended to leave
this value at the release version of the first install of this system.
Before changing this value read the documentation for this option
(e.g. man configuration.nix or on https://nixos.org/nixos/options.html).
system.stateVersion = "23.05"; # Did you read the comment?
