*Sigh*. Did anybody even read the PredictableNetworkInterfaceNames page?
Physical-device-location-based names aren't even the default – they're just a safe fallback, if your BIOS doesn't supply sane interface numbers.
Plus, how to go back to ethX is well-documented.
* If you have to type in the name more than once, even in an emergency situation where you'd have to setup a route by hand, you're doing something wrong. If necessary, I'd type x=ethxMACaddr once, then refer to the thing by $x, which is even less typing than eth0. Or I'd use the shell's command history; even the busybox shell has one, these days.
* What's worse – a bit of an inconvenience, or having your internal network suddenly exposed to the whole world, because a timing quirk re-ordered your interfaces? Give me (and Lennart) a break here.
I do not want an OS which defaults to doing unsafe, random, and/or race-condition-prone things when it boots. Neither WRT my disk drives (remember the switch to UUIDs?) nor my network interfaces.
