<pre>I'm running systemd 216 and have the following network file in order to get
DHCP on my ethernet and my wireless interface (it's a laptop and I'm using
wpa_supplicant for the wireless interface):
[Network]
DHCP=v4
Using the new networkctl tool I noticed that the loopback interface was in
SETUP "configuring" and networkd is indeed sending DHCP requests on the
loopback interface.
I know that this is technically correct since the loopback interface matches
because of the missing [Match] section. But imho this is kind of unexpected
behaviour, especially since I can't think of a reason why one might want to
configure the loopback interface.
Feel free to close this if you don't consider it a bug, but maybe there should
at least be a warning in the man page that a missing [Match] section also
matches lo.</pre>
