Bug#414287: me too

[Daniel Pocock <daniel@pocock.com.au>]

My box had lenny (installed in December, before the official release), I 
just did:

 apt-get dist-upgrade

It upgraded the box from 2.6.26-1 to 2.6.26-2

I did a reboot to get the new kernel

On booting, eth0 became eth0_rename_ren

I looked at:

  /etc/udev/rules.d/70-persistent-net.rules

and found each MAC listed multiple times, with variations of eth0_rename and eth0, etc

I deleted the file completely, rebooted again, and found the interfaces eth1, eth0_rename, eth2_rename and eth3_rename on my system, and each of these describe once in /etc/udev/rules.d/70-persistent-net.rules

I edited the file by hand, remove _rename from each of the names, rebooted again and now I have eth0, eth1, eth2, eth3

Now for another reboot - and I still have eth0, eth1, eth2, eth3 now.

My biggest concern is that booting without any /etc/udev/rules.d/70-persistent-net.rules gave me three interfaces with _rename appended to their names.

One other comment, not sure if it could be related to the issue in any way, but this is a Xen dom0 box, and Xen does it's usual tricks renaming interfaces, but not until after the udev setup.
