Comment 16 for bug 1031065

There is an 'eth0' defined in /etc/network/interfaces.
And, there is a network device eth0

$ sed -e "/^$/d" -e '/^#/d' etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp

$ ls -l /run/network
total 4
-rw-r--r-- 1 root root 16 Sep 12 18:33 ifstate
-rw-r--r-- 1 root root 0 Sep 12 18:33 ifup.eth0
-rw-r--r-- 1 root root 0 Sep 12 18:31 ifup.lo
drwxr-xr-x 2 root root 40 Sep 12 18:33 static-network-up-emitted

Note, that eth0 came up 2 minutes (120 seconds) after lo.
