Subject: WiFi stops working if managed with NetworkManager after migration
 to unprivileged guix daemon

Hi!

I tried to opt-in into using guix daemon in unprivileged mode using:

> (modify-services %base-services
> 		 (guix-service-type config =>
>                                     (guix-configuration (inherit config)
> 							  (privileged? #f))))

After reconfiguration (and finish of the task changing owner of store to
guix-daemon), I rebooted system to found out that WiFi not working anymore.

I use NetworkManager for the network configuration, with pretty much the
default configuration:

> (service wpa-supplicant-service-type)
> (service network-manager-service-type
>          (network-manager-configuration (vpn-plugins (list
>                                                       network-manager-openvpn))))


In logs I can see the following errors:

Looks like NetworkManager doesn't like a non-root owner of plugins.

After reconfiguration back to the priveleged guix-service-type,
NetworkManager is back to normal:

Oh but that one should be fine.
