I was actually ranting about this on IRC last night (yeah now my laptop has two enp* interfaces and enx[MAC])..

One thing I like about OpenBSD is that buses are scanned and drivers probe in order and there's no race between drivers coming up. Unless your hardware is physically tampered with or broken, all interfaces come up with the same name across reboots. Linux isn't like that (even if you don't touch your hardware, interfaces could swap across reboots), so you need to do something about it.

As is typical on Linux, the default is unergonomic and if you want something nice, you're on your own to make it so.

If you already have userspace daemons responsible for device insertion and naming, it really wouldn't have been so hard for it to e.g. automatically add a config file / database entry for each interface the first time is seen. So the devices that came up as eth0 and eth1 are still eth0 and eth1 on the next boot; if I unplug eth0 and add a new card, the new one would be eth2 because eth0 is still reserved for the first card I had.
