Hmm... Ubuntu renames interfaces based on their MAC address, which are listed
in /etc/iftab. Dunno about other distributions.
If there are so many interfaces and they were just reordered, this could be
caused by a (non-existant) change in link order. Or (I don't know how) it
could derive some way from the fact that interfaces are initialized later
(instead of __initcall, late_initcall is now used).
