You basically have three options:
-1. You disable the assignment of fixed names, so that the unpredictable kernel names are used again. For this, simply mask udev's rule file for the default policy: `ln -s /dev/null /etc/udev/rules.d/80-net-setup-link.rules`
+1. 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`
1. 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)|http://www.freedesktop.org/software/systemd/man/systemd.link.html]] for more information.
1. You pass the net.ifnames=0 on the kernel command line
