At the moment, the best thing would be to ask users to explicitly copy/modify/@load the sample config file somewhere in the site/ dir.
But a new feature could be added to bro-pkg that allows package authors to specify a list of config files in their bro-pkg.meta. Then on install/upgrade/remove, if a user has made modifications to any of those files, they can be warned/prompted about how to proceed (show a diff, ask to overwrite or keep modified version, etc.). This seems a common way to handle config files in the package management scene.
Would such a feature work for you?
