If you're referring to the ethernet device being eno1 or enWhichUSB22 instead of eth0, or wxbd3 or wl21Poettering423 instead of wlan0, I prefer the new way. Here's why: A very short shellscript, using the ip command multiple times, positively identifies the one and only wifi device on a computer, no matter where it's plugged in. I use that shellscript in all my runit run scripts, so I no longer need to specify a device name at all. On computers with multiple wifi devices, an additional piece of info is necessary. My shellscript's about 6 lines long, and adding a few more lines would make it accurate regardless of which naming convention is used. I put that shellscript on the DNG mailing list a year or two ago.
