The physical device that is assigned to your software settings in
/etc/network/interfaces can be modified in
/etc/udev/rules.d/70-persistent-network-settings

This is from memory. Get into the /etc/udev/rules.d/ directory, and
you'll see the file. You can either delete it (it's recreated upon
reboot) or edit the ethX settings. It's straightforward.

In the Ubuntu world, you can install and run oem-config prior to
imaging and your usernames and network settings are reset.
