/etc/network/interfaces & /etc/sysconfig/network-scripts aren't part of NetworkManager (the directories don't even exist on my machine).

You should probably check out `systemctl list-units` to see what is actually enabled and running on your machine.

Thanks, that's a pretty nifty systemd command[1]. Sadly my confusion is only furthered, since I'm seeing both target files and daemons (although maybe they're both considered 'units' in systemd) and now a new name ("networkd") joins the fray. No sign of NetworkManager at least.

What's also interesting is I've somehow managed to have the networkd-wait-online.service fail, despite having an internet connection.

This is mostly a curiosity at this point, nothing's broken - but it is a really humbling experience to realize how little I know about the modern Linux network stack after "using" desktop Linux for a decade or so.
