No netctl here :)

I systemd-networkd enabled on boot and 3 files in /etc/systemd/network

This last one is sort of a hack to bring the network up as it shows up,
I suppose systemd-nspawn should do it by itself, this might be a bug,
unless there is a good reason not to bring the network up automatically.

Inside the container I do manual setup of the network address since I'm
not actually booting it.

Mind you that you may have to do systemctl daemon-reload (not really
sure if this one is needed) and restart systemd-networkd for any changes
to make effect.
