Hello Everyone,

  I had the same problem with interface naming as it
moved my wireless card from wlan0 to eth1 upon
upgrade.    Mike thanks for the heads up on that.  

Thanks,
J

I had a similar problem when the system started using
/etc/iftab to
name network interfaces.  I'm not sure what the
easiest way to fix it
is, but I used "ifconfig -a" to get the hardware
addresses and edited
/etc/iftab to give them permanent names, like this:

  # This file assigns persistent names to network
interfaces. See 
iftab(5).
  eth0 mac 01:23:45:67:89:ab
  eth mac  02:46:8a:ce:13:57
