Hey,
I've recently been using systemd-networkd to great success on a few of
my machines here. However I ran into an interesting problem on at least
2 machines so far. I've included the output of journal for
systemd-networkd with Environment=SYSTEMD_LOG_LEVEL=debug as was
suggested on another post. In addition the only network file I have
configured is em0.network which contains the following,
$cat /etc/systemd/network/em0.network
[Match]
Name=em0
[Network]
DHCP=Yes
The journalctl for systemd-networkd after bootup is,
-- Logs begin at Mon 2012-12-31 20:02:09 PST, end at Tue 2015-02-03 10:57:09 PST. --

Notice that only a bunch of my fake devices, hand made bridges, and such
are found during bootup. However, if I manually restart networkd then it
finds all the devices,

Any suggestions as to why networkd doesn't (a) find em0 during bootup,
or (b) configure it when it does appear after boot up?
Thanks for all your work, much appreciated.

Jake
