I'm just reading this now.It should either go away completely, or we should disable the new setup. :-) For the record, the new default setup only works if (IIRC from the thread on systemd-devel) the BIOS exports the slot number for the card. Not all do (mine definitely does not -- the NIC sysfs directories do not have a acpi_index or index attributes, and there are no entries in /sys/bus/pci/slots at all). From the wiki page, that eliminates 1) and 2). 3) is the same old by-path persistence, and because it's encoded into the NIC name, it has the same length limit of 15 bytes. So anything on a USB bus just isn't going to work, both because it changes when you change hub ports, and because too many hubs between the PCI device and the NIC will make the name too long. That leaves 4), by-mac, which only works for NICs that have unique MACs. (FWIW I do think we should get rid of the NIC rename stuff, but I think we should replace it with a shell script to look up an arbitrarily-long identifier from the udev database instead, and translate that into an eth* or wlan* or whatever name. That ID can be a storage-style path, a MAC, or any other unique identifier that the script knows how to dereference by mapping to a udev property. I threw something together a few months back, but never submitted it to contrib/ or anything like that.)
