- Usually, netplan's systemd-generator enables systemd-networkd and
systemd-networkd-wait-online on boot. But netplan configuration is not
yet generated at that point by cloud-init. Cloud-init generates in the
network-pre.target and expects the network.target /
network-online.target to work. These are already part of the ongoing
systemd transaction, thus cannot be injected into the boot-sequency by
cloud-init local mode. Therefore make sure cloud images include
networkd in the initial boot transaction.
- src:systemd will shortly not enable networkd unconditionally by
default.

In xenial, eth0 won't exist (as we've moved to systemd's predictable interface
naming), and even were it to exist, cloud-init would handle configuring it on
boot.
