@https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/:I don't like this, how do I disable this?
You basically have three options:
You disable the assignment of fixed names, so that the unpredictable kernel names are used again. For this, simply mask udev's .link file for the default policy: ln -s /dev/null /etc/systemd/network/99-default.link
You create your own manual naming scheme, for example by naming your interfaces "internet0", "dmz0" or "lan0". For that create your own .link files in /etc/systemd/network/, that choose an explicit name or a better naming scheme for one, some, or all of your interfaces. See systemd.link(5) for more information.
You pass the net.ifnames=0 on the kernel command line
