And *why* random NIC names? Quick, you've got servers from 5

As someone else had stated, it's not related to SystemD but
Fedora/RHEL has changed the way they handle some things. NICs, for
instance, are no longer named after the device number (eth0, eth1,
eth2, etc.) but after the *driver* name. Yes, it's a change but it
also makes sense. IIRC this is how FreeBSD handles NIC names.
It's true that FreeBSD names their network interfaces after the driver.
But the consistent device naming in Linux comes from slot index
numbers, physical location and even the MAC (if so configured), and
not what driver it uses.

Okay that makes sense.
