This reverts commit 8401290976.
We are reverting this because some users may want to use predictable
device names and may not even use Debian. However, after some
investigation we have found a couple of bugs in dhcp-all-interfaces on
Debuntu distros. The parent change corrects those bugs. Additionally new
Linux kernels emit "move" events to udev when interfaces are renamed to
their predictable name. Support this "move" in the dhcp-all-interfaces
udev rules. Making these changes appaers to produce functional images
for Debian users using predictable device names. If predictable device
names are not desired turning them off is straightforward and release
notes are updated to give users the info they need to do that outside of
this element.
