In https://blueprints.launchpad.net/ubuntu/+spec/foundations-w-networkd-vs-ifupdown we want to provide networkd as a viable option for Ubuntu, in particular server/cloud land. This requires some integration with existing packages, in particular calling the /etc/network/if-up.d/ and if-post-down.d/ scripts, similar to what NetworkManager does.

I would like to land this in wily still, so that people can experiment it and we still have some time to tweak it for 16.04 LTS:

As we don't currently use (or even advertise) networkd in Ubuntu, the risk of this is very low IMHO. The main regression risk is if that would somehow influence/break interfaces managed by ifupdown or NetworkManager, but the above changes test if the interface is managed by networkd.
