Comment 2 for bug 1870346

In my opinion, the provider of network configuration to an instance (image) should not have to "know" that the image uses networkd, NetworkManager, ifupdown, wikid.... They just declare "make the networking like this".

The operating system inside implements API. Anything else just cannot work. For example, a cloud provider that implements "bring your own image" can't possibly know what an image uses to configure its networking.

cloud-init should either do the right thing, or error saying "Cannot implement network configuration."
