Along these lines, netplan in Ubuntu is seriously confusing. That's the set of scripts that rewrites most of your network config in /etc with stuff generated from some new set of YAML config files. I'm willing to believe netplan is a Better Way to configure networking, but the kludge of having it rewrite long-understood config files in /etc is really awful.
I tried to get on baord with netplan, I really did. I thought it was a redhat inspired systemd-esque invasion.
Turns out it's an 'upstart' type ubuntu crapfest that's unlikely to survive as long as 20.04.
I wouldn't mind, but the very first machine I tried to configure with it was an ntop machine, I wanted 2 interfaces to come up with no IPs attached. Turns out it's not possible.
