So which one of these two was the current Fedora?  None?  Oh...

I know that you can change an interface name.  It is not so easy
to do that if it is tied to a MAC of a interface.  Sometimes this
is actually a PITA when, for whatever reasons, you do want to change
these names and you have to fish out where this connection was
recorded.

If you will look closer then in /etc/sysconfig/network-scripts/ifcfg-*
files there is HWADDR and it was automatically filled for quite a
while now although not from "always".  If those configuration files
are not used then /etc/udev/rules.d/70-persistent-net.rules are
doing a similar thing.

OTOH 'man ifrename' and /etc/iftab were available when needed I do
not remember now for how long.  The only thing is that once a
network interface went up then it is too late for renaming.
