And my point is that once the machine has booted and created the udev
rule file, it will also have created matching MAC entries in the
ifcfg-* files.  It is as much work to remove them as to use them as
the starting point when adding the rest of the settings.  Except maybe
in your unusual case of knowing a running system is going to be
moved/cloned to known new MACs.

Sure, but there is always more than one way to do things. And like the
people who sell investments are fond of saying, "past performance is
no guarantee of future results".
