Not false, but configurable, and linked from the news item -- nobody stopping you from eg. using MAC addresses instead of PCI slots for defining the names, just like one would have renamed them using MAC with 70-persistent-net.rules >> If /etc/udev/rules.d/80-net-name-slot.rules is a empty file, or if it's a >> symlink to /dev/null, the new names will be disabled and kernel will do >> all the interface naming, which will be random. > > Avoid spreading FUD about naming being random. Thanks. Not FUD, but a fact, depends on the driver code (in kernel) if it'll change or not That's random enough as we can't force people to track kernel source tree and drivers code
