Those fix similar problems but not exactly the same ones. The udev
persistent rules get you when you move an image from one machine to
another or swap out failed hardware and suddenly you have no network
because eth0 suddenly became eth1. And as I noted, not only network
device names but CD drives as well are impacted. The fixes you suggest
solve the equally annoying problem of eth0 or wlan0 unexpectedly turning
into a string of gibberish after an upgrade.

They are turning everything into a UUID or similar string of untypable
gibberish. It is almost like they don't want you to use the command
line directly anymore. Nah, that couldn't be it, right?
