We'd like to consider the network.target to be up only once we have
connected to the network (so that other services can rely on this).

I only fixed this up as it was buggy when I found it, but it might be
that this behavior is not desired at all (I don't use this stuff). How
would you expect this to work?

For your reference:

    systemd: wait for network to come up

    We need to make sure no the systemd services are only considered
    started when the network is actually up. Otherwise, things relying
    on the network don't know when they can start.

    This means that we need to use Type=forking or Type=oneshot, and in
    the case of ifplugd we must daemonize and wait for the daemon to be
    ready before we continue.

    Also do some minor cleanup:
     - don't include env files that are not used
     - don't ignore return values

    systemd: pull in network.target

    It is not enough to order ourselves Before network target, we must also
    make sure it is pulled in. This means that anything that needs the network
    to be up before they start can order themselves After=network.target.
