There doesn't seem to be a reason to force users to write
(service iptables-service-type
(iptables-configuration))
instead of simply
(service iptables-service-type)
This patch provides a default value for the iptables-service-type.
* gnu/services/networking.scm (iptables-service-type): Set default-value.
