They are trying to make sure that ethernet ports are predictably labeled. This means they want to look at the back of the hardware and identify eth0 without the use of software. Most devices are assigned labels in linux as they are found and the order in which they are found is often different from how they are arranged on the computer. There are also situations in which the order can change after a reboot which throws a wrench into everything.
The example of this is a server with 4 ethernet ports lined up in a row, but when linux sees them in software the order gets jumbled. If you were too boot up slackware on one of these servers you might see something like this.. Port 1 - eth1 Port 2 - eth0 Port 3 - eth3 Port 4 - eth2 clearly the ethX names make no sense given the physical labeling on the back panel of the server. As a system builder, you are supposed to take extra steps to set things in stone but end users typically only have 1 or 2 ports so it doesn't matter. It's just stupid because like Russel said it only affects a small portion of the total linux user base and from what I'm reading their solution doesn't even do anything useful because systemd is still going to provide wildly different results from one system to the next. In fact, the only real change here is a loss of portability which was the original gripe in this thread. If Keith rewrites his scripts to use the 'enp2s0' naming convention those scripts will fail if he moves to a system where the ports show as "eno1".
