I understand why the names come up jumbled on bootup, but there is no excuse
for udev not being able to properly rename them as requested

ask Kay Sievers , he is able to explain it to you too

in short:
the kernel may also rename the devices as they come up
if kernel want make one nic to eth1 and udev at the same time another one -> collision

That's fine.  Udev can just detect the collision and try again, potentially
moving the other one to a new name.  That is what it has done for years,
in between bugs that caused eth0.rename devices to be left lying around.

Thanks,
Ben
