NetworkManager-wait-online.service times out

[raboof]

Describe the bug

When I 'nixos-rebuild switch', this takes a long time, as NetworkManager-wait-online.service is timing out. The network seems to work fine, though.

I set networking.networkmanager.logLevel to DEBUG, but this didn't turn up anything obvious in journalctl yet.

See #247608.

I use:

systemd.services.NetworkManager-wait-online = {
    serviceConfig = {
      ExecStart = [ "" "${pkgs.networkmanager}/bin/nm-online -q" ];
    };
  };

Thanks for the reference! I don't think I have networking.useNetworkd enabled, though - unclear whether it's the same issue?

I use:

systemd.services.NetworkManager-wait-online = {
    serviceConfig = {
      ExecStart = [ "" "${pkgs.networkmanager}/bin/nm-online -q" ];
    };
  };

haven't checked what that does, but it indeed does appear to make switching fast again :)

Yeah I actually took it from https://github.com/NixOS/nixpkgs/issues/180175#issuecomment-1658731959. Found it now.
