Since last systemd update dhcpcd no longer updates resolv.conf

[Manuel Reimer <Manuel.Spam@xxxxxxxxxxxxxx>]

Hello,

since the last systemd update I have to "systemctl restart dhcpcd@..." 
every time I boot my system.

What do I have to do to get sure that dhcpcd updates /etc/resolv.conf on 
the first time?

Thanks in advance

Manuel
