A recurring problem when helping new users getting started with running Bitcoin Core is the config file location; a lot of uncertainty is caused by the config file and the folders it should go in not being created automatically by the installation process.

It does not even have to be the full sample as found in contrib, just having an empty config file (or one with a minimal comment directing people to the sample file) created by default would ease the assisting of users on OSes one is not familiar with, as it would be easier for them to verify that they are putting their OS-agnostic configuration in the correct OS-specific location without some unnecessary trial-and-error.
