Ugh no. Document it in the release notes and/or README.Debian, please, not
as a nagbox in the middle of an upgrade.

Which do you think is the common case -- a system with more than one network
interface where it's necessary to preserve interface ordering across
reboots, or a system where the admin will frequently change out the network
hardware and need to reuse the same interface names?
In the absence of kernel guarantees about device ordering (as is the case
with 2.6), the current udev implementation gives you the first at the
expense of the second. I believe this correctly optimizes for the common
case.
