Well, I still believe this is a problem with udev. CCing Marco.
> Summary of the problem:
>
> After an installation of Debian on the Linksys NSLU2, the system is
> inaccessible because the USB ethernet interface is renamed
> eth1_rename.

> Background:
>
> The NSLU2 is an ARM based network available storage device. Support
> for installing Debian on this system has been added to etch. The NSLU2
> has a single built-in ethernet adapter for which a driver has been
> written and included in the Debian 2.6.18 kernel. However, Debian
> installer images cannot use this driver, because the network processor
> engine (NPE) in the IXP4xx CPU requires non-free microcode. Therefore,
> a USB to ethernet adapter is required to install Debian.

> Problem description:
>
> Debian installs without problems using the USB to ethernet adapter.
> During the installation, a udev rule is written which names the USB to
> ethernet adapter to eth0:
