 The rationale for this is that we are likely to require multiple
 network interfaces for use cases such as baremetal and there is no way
 to know ahead of time which one is which, so we will simply run a
-DHCP client on all interfaces (except lo) that are visible on the first

 The script /usr/local/sbin/generate-interfaces-file.sh will be called
 early in each boot and will scan available network interfaces and
