@emilazy:matrix.orgemilyespecially for remote it's hopeless, but even locally there can be all kinds of layers between an enabled service and what actually ends up being used for DNS resolution14:23:49
@hexa:lossy.networkhexa (clat on linux when) so one thing I could do is check for networking.resolvconf.useLocalResolver 14:24:14
@hexa:lossy.networkhexa (clat on linux when)

the other thing, that I found super awful was

         lib.any (with config; [
          services.bind.enable
          services.dnsmasq.enable
          services.kresd.enable
          services.unbound.enable
          services.pdns-recursor.enable
        ]);
