/etc/resolv.conf *can* be a symlink, or not. Depends on what you've installed. https://wiki.debian.org/resolv.conf This page doesn't talk about iwd... partly because I'd never heard of it at the time I wrote most of the content on that page. I've certainly never used it, and I don't know how it works, how resolvconf interacts with it, etc. It also doesn't talk about systemd-networkd, or network-manager. If some people out there know how those things work (in *detail*) and are able to contribute to the wiki page, that would be great.
