@pemensik which is at the same time good and bad. If I was trying to debug a #DNS issue in one app that uses #glibc's 3-servers resolver with a tool that uses them all, it might as well work for the tool and not the app. I guess one has to be aware of that, hence my post.
That's probably why it makes sense to use #resolved with the stub handling of `/etc/resolv.conf`; that and the fact that can do much better resolving, if configured correctly.
