Right. Nothing should be relying on the actual device name, they should be relying on the MAC address or some other UID of the actual device. In many distros, the config scripts depend on a set name, but only _AFTER_ they have check the devices MAC address, matched that up with a MAC->devname table, and renamed the device. That's somewhat sane, but scripts cannot just rely on the device name without checking some other unique attribute of the device.
