From: Josep Puigdemont Date: Wed, 4 May 2016 17:58:56 +0200 Subject: [PATCH] transplant: Generate extra interfaces config file The DEA override may contain a IFCGF_ section in its 'fuel:' section, containing the necessary keys to produce a ifcfg- file, like in this example: fuel: IFCFG_ETH1: device: eth1 ipaddress: 10.0.1.10 netmask: 255.255.255.0 gateway: 10.0.1.254 FIXME: In order for Network Manager to use the newly added interfaces for outgoing traffic and honor their GATEWAY setting (e.g. if we just added one public interface), the default route on admin iface (most of the time called eth0) should be disabled. For now, we assume the admin interface is always "eth0".
