I don't understand why "init.d/networking restart is deprecated" is
scaring off people? It is a matter of fact! Reading the results will
give all answers a user want.

Well, you must be sure that all interfaces in your system get their
assigned names. To make sure they will, you have to define udev
rules, probably by hand if not done by udev itself ( i.e.
/etc/udev/rules.d/70-persistent-net.rules).

On modern systems running systemd (and in some circumstances
sysvinit sytems as well) you may get unwanted if names. So
users have to keep their eyes on what is deprecated (which may be
valid only for future updates) and can be obtained on legacy
installations as well. Just FYI:
https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/
So rely on the kernel in naming network interfaces is nothing else
as a guess.
