According to the man page that would not prevent some other service = adding other resolvers. >>> When was resolveconf tasked with overwriting the resolver.conf file? >>> Was this part of moving to FreeBSD 12? >>=20 >> Earlier than that. I can't remember whether it was 11 or 10. That is odd, because I know that my server was not using the quad9 DNS = when I was on 11.2, though I cannot say that it wasn't;t using = "resolveconf" back then. > I was using 10.2 when I started using resolvconf.conf. As far as I know I never started using resolvconf as I had never heard = of it before a few days ago when I looked at resolve.conf wondering why = I was hitting 9.9.9.9 on occasions and saw "created by resolveconf" and = went investigating. I still do not know where the quad9 DNS that was added came from (simply = editing resolve.conf did not work, it was immediately put back).
