With fire. Seriously. Reason 1: anything that doesn’t honor kernel “sysctl” settings deserves to die.
Many thanks to “Yoon’s blog” and his post “https://www.naut.ca/blog/2018/12/12/disabling-systemd-networking/index.html”

Recap:
Install ifupdown to replace networkd:
apt-get install ifupdown

Now edit /etc/network/interfaces.

Disable networkd:
systemctl stop systemd-networkd.socket systemd-networkd networkd-dispatcher systemd-networkd-wait-online
systemctl disable systemd-networkd.socket systemd-networkd networkd-dispatcher systemd-networkd-wait-online

apt -y purge netplan.io

Disable resolved (might as well!):
systemctl disable systemd-resolved.service
systemctl stop systemd-resolved

Create your own /etc/resolv.conf. Make sure to “rm /etc/resolv.conf” first – it’s a dang symlink into the ugly.
