stubby ignore extra argument

[randomstuff]

I spent quite a lot of time trying to undertsand what was wrong with my stubby instance.

It turns out I was using:

stubby stubby.yml

Instead of:

stubby -C stubby.yml

Apparently, extra arguments are ignored without error and without warning:

stubby -C stubby.yml  I can pass extra argument if I want

As a consequence, the user might think he's actually using a carefully chosen upstream servers but might instead be using the default ones.

Acknowledged - we should handle this better.

But I think in your specific case you should at least have seen this: WARNING: No Stubby config file found... using minimal default config (Opportunistic Usage)
