Subject: [PATCH] services: wpa-supplicant: Extend to support configuration
 parameters.
Date: Thu, 20 Sep 2018 17:42:14 +0200

This allows using WPA Supplicant "standalone" without an additional
network manager.  The default configuration is unchanged.

* gnu/services/networking.scm (<wpa-supplicant-configuration>): New record type.
(wpa-supplicant-shepherd-service): Pass configuration records to the daemon.
(wpa-supplicant-service-type): Adjust accordingly.
* doc/guix.texi (Networking Services): Document the new service type.

I have done some testing and the default configuration seems to work
