wpa_supplicant as a 'networking' service

[Jakub Czajka]

Hi,
I moved to Guix recently. I'm trying to remove network-manager from
%desktop-services.
(modify-services %desktop-services
  (delete network-manager-service-type))
However, I get an error:
>guix system: error: service 'ntpd' requires 'networking', which is not
provided by any service
I see the problem has already been discussed [1] and there was a solution
proposed.

However, I'd like to use ntpd with wpa_supplicant. wpa_supplicant is part
of %desktop-services but I guess it's not considered networking? How can I
set wpa_supplicant to be considered 'networking'? I'm pretty sure this
setup (ntpd + wpa_supplicant) worked with my previous distribution.
