- only affects systemd-networkd-using builds (MINIMAL images?) - does NOT affect NetworkManager - this allows network administrators to give out IPv6 addresses over DHCPv6 based on the MAC address (which should be stable) instead of systemd's own notion of it's "DUID", which is based on the machine-id and changes on every redeployment
