Comment # 16 on bug 931165 from Dr. Werner Fink

(In reply to Felix Miata from comment #15)

Hmm ... with net.ifnames=0 I see

 linux-8jdz:~ # ifconfig -a
 eth0      Link encap:Ethernet  HWaddr 08:00:27:2C:1F:66  
           BROADCAST MULTICAST  MTU:1500  Metric:1

           RX bytes:21652 (21.1 Kb)  TX bytes:21652 (21.1 Kb)

and also get

 linux-8jdz:~ # ll /etc/udev/rules.d/
 total 4
 -rw-r--r-- 1 root root 631 May 19 08:52 70-persistent-net.rules

which I now remove to (re)boot back into ``predictable'' mode.
