Systemd predictable network interface names are awesome.
Not only I get easy to remember names like enp2s0f0u7u3c2 but I _also_ get to experience a machine not coming back up after reboot because a new (non-NIC!) PCIe card caused existing names to shuffle around.
@q3k I really like #OpenBSD's approach. Usually, you configure network interfaces in a file called /etc/hostname.<if> where <if> is the name of the interface.
To avoid the renaming problem, you can also name the file /etc/hostname.XX:XX:XX:XX:XX:XX so it's bound to the MAC address.
