Comment 24 for bug 1649931

@racb

I verified systemd 229-4ubuntu17 with both ifupdown and networkd configuration.

The specific packages and features is somewhat complicated due to
the different scenarios and change in networking behavior in yakkety+

I've attached a chart with details. Also viewable here:

The tl;dr is for Xenial, we won't need another SRU as
systemd-resolved is not enabled to manage DNS, rather
resolvconf still controls /etc/resolv.conf

In Yakkety+, systemd-resolved ends up owning /etc/resolv.conf
and employs resolvconf to register itself therein.
