+Note on `interfaces`:
+By default, a linode is created with a single network interface (eth0) which is
+assigned a public IP address.  If your test linode requires another network
+interface (eth1) to mock a backend network, you may declare it within the platform
+definition.  If you do this, you should declare _all_ network interfaces, as
+shown below.
