Right. I meant that in most cases one wants the network to be
considered up when all the interfaces (that should start at boot time)
are configured.
You can probably set up a second (third, fourth, ...)
"systemd-networkd-wait-online.service" for other interfaces. It's
probably be more useful and practical if there were an option to set
the interfaces that this service would use to enable
"systemd-networkd-wait-online(a)ethX.service"
