network: don't add "no-resolv" if we still need DNS servers from resolv.conf It was pointed out here: https://bugzilla.redhat.com/show_bug.cgi?id=1331796#c4 that we shouldn't be adding a "no-resolv" to the dnsmasq.conf file for a network if there isn't any <forwarder> element that specifies an IP address but no qualifying domain. If there is such an element, it will handle all DNS requests that weren't otherwise handled by one of the forwarder entries with a matching domain attribute. If not, then DNS requests that don't match the domain of any <forwarder> would not be resolved if we added no-resolv. So, only add "no-resolv" when there is at least one <forwarder> element that specifies an IP address but no qualifying domain. 2017-03-17 16:25:43 +00:00			`<network>`
