For information: You need to run:
 "systemctl enable NetworkManager-wait-online.service"

This sets systemd to wait for the network to be up before generating
network.target. Programs then need the network up, such as ypbind, now
wait until the network is actually up.

Why this is not the default I will never know. I guess most developers are
using individual Laptops and not using servers with multiple clients :)
