"systemd-resolved - Network Name Resolution manager" - man systemd-resolved

systemd-resolved enhances (ie: interferes with) old school simple methods of managing DNS on a linux system. The way it reads the /etc/resolv.conf file as either a file or symlink alters the behavior of the service, which is a new mechanic that can have unexpected effects if you're not familiar with it.
