Favor the configuration in "configFile" over "config" to allow
"configFile" to override "config" without a system rebuild.

Add a "persistentKeys" option to generate keys and addresses that
persist across service restarts. This is useful for self-configuring
installation media.


Motivation for this change

The Yggdrasil module should support persistent addressing without manually generating keys.

As for changes the priority of configuration values between the configuration in the nix store and mutable configuration, I thought it was more intuitive to favor the mutable (though use of mutable configuration is not encouraged). I don't have a strong opinion on this and I can change it back if its is an issue.

Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Ensured that relevant documentation is up to date
  • Fits CONTRIBUTING.md.
