Correct, it's just the goal, which causes everything that actually
brings up the network to start before it.

That's part of it, but also /etc/init.d/networking, i. e.
the autogenerated networking.service.

I committed a fix for this:

  http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/commit/?h=experimental&id=c90467c1b2909

This is fairly harmless on a standard installation as nothing hooks
into this target, but fairly important on systems which do rely on it,
so I'll also apply this to the master branch for Jessie.

Thanks,

Martin
