Cockpit parameter services.cockpit.port is not honored anymore

[elratt0r]

Describe the bug

When setting a port with services.cockpit.port, the port stays on the default tcp/9090.

Steps To Reproduce

Steps to reproduce the behavior:

1. Enable cockpit package and set a different port

{ pkgs, ... }:
{
  environment.systemPackages = with pkgs; [
    cockpit
  ];
  services.cockpit = {
    enable = true;
    port = 80;
  };
}

2. switch to config

3. Observe "Listen" in systemd status

[root@nixos:~]# systemctl status cockpit.socket
● cockpit.socket - Cockpit Web Service Socket
     Loaded: loaded (/etc/systemd/system/cockpit.socket; enabled; preset: ignored)
    Drop-In: /nix/store/zagkwj3h5aa5795qi46xjx64bkmwgqd1-system-units/cockpit.socket.d

   Triggers: ● cockpit.service
       Docs: man:cockpit-ws(8)
     Listen: [::]:9090 (Stream)
         IP: 0B in, 0B out
         IO: 0B read, 0B written
      Tasks: 0 (limit: 9425)
     Memory: 8K (peak: 1.8M)
        CPU: 33ms
     CGroup: /system.slice/cockpit.socket

Expected behavior

Cockpit socket should listen on the port assigned in the configuration.

Additional context

Changes in PR 369266 removed some generators, see also here in detail.

Workaround:

  systemd.sockets."cockpit" = {
    socketConfig = {
      ListenStream = 80;
    };
  };

Does not overwrite the listen on 9090 but at least adds another extra listening socket.
