Comment # 5 on bug 1155690 from Aaron Puchert

Hmm, if you're using NetworkManager, that's not very surprising:

$ systemctl list-dependencies --after network.target
network.target
��� ������NetworkManager.service
��� ������network-pre.target
$ systemctl list-dependencies --after network-online.target
network-online.target
��� ������network.target
���   ������NetworkManager.service
���   ������network-pre.target

So it doesn't make a difference. The dhclient is a child of NetworkManager and
might be started later than that. If you use wicked, could you post the outputs
of these two commands? If not, maybe try wicked.
