Error waile activating config (macOS)

[SolidRhino]

I get the following error when I try to activate an existing config on macOS:

nix run .#activate

       - Previously, some nix-darwin options applied to the user running
       `darwin-rebuild`. As part of a long‐term migration to make
       nix-darwin focus on system‐wide activation and support first‐class
       multi‐user setups, all system activation now runs as `root`, and
       these options instead apply to the `system.primaryUser` user.

       You currently have the following primary‐user‐requiring options set:

       * `homebrew.enable`
       * `system.defaults.dock.autohide`
       * `system.defaults.dock.show-recents`
       * `system.defaults.dock.wvous-bl-corner`
       * `system.defaults.dock.wvous-br-corner`
       * `system.defaults.dock.wvous-tl-corner`
       * `system.defaults.dock.wvous-tr-corner`
       * `system.defaults.finder.AppleShowAllExtensions`
       * `system.defaults.finder.FXEnableExtensionChangeWarning`
       * `system.defaults.finder.FXPreferredViewStyle`
       * `system.defaults.finder.FXRemoveOldTrashItems`
       * `system.defaults.finder.QuitMenuItem`
       * `system.defaults.finder.ShowPathbar`
       * `system.defaults.finder.ShowStatusBar`
       * `system.defaults.finder._FXShowPosixPathInTitle`
       * `system.defaults.finder._FXSortFoldersFirst`
       * `system.defaults.finder._FXSortFoldersFirstOnDesktop`
       * `system.defaults.trackpad.Clicking`
       * `system.defaults.trackpad.FirstClickThreshold`
       * `system.defaults.trackpad.SecondClickThreshold`
       * `system.defaults.trackpad.TrackpadRightClick`

       To continue using these options, set `system.primaryUser` to the name
       of the user you have been using to run `darwin-rebuild`. In the long
       run, this setting will be deprecated and removed after all the
       functionality it is relevant for has been adjusted to allow
       specifying the relevant user separately, moved under the
       `users.users.*` namespace, or migrated to Home Manager.

       If you run into any unexpected issues with the migration, please
       open an issue at <https://github.com/nix-darwin/nix-darwin/issues/new>
       and include as much information as possible.

How can I fix this?

Is this reproducible in https://github.com/srid/nixos-unified/tree/master/examples/macos ?

Or just your config?

This seems related: srid/nixos-config#89

This seems related: srid/nixos-config#89

That is the right fix. Can you add this to nixos-unified, or must this be added on a per flake bases?
