Here is my reason: It seems needless to have if, the value of ipv6_network_interfaces could just be checked against to see if it is anything other than null. In the default case it is already set to auto and I propose removing ipv6_enable and change ipv6_network_interfaces to be null and if it is anything other then null ipv6 will be enabled in the same fashion it is now but less variables to have to specify in the long-run. This is just a short quick answer that I did not get to involved with yet but I see this as a "if the interface is specified then you obviously want ipv6 to be enabled" and brings it a little closer to the functionality of ipv4 not having to specify ipv4_enable. Just a thought in a hay stack. Regards, -- jhell
