Should this only happen in dev mode?

Should we be worried about using the sync versions of these calls instead of the async ones?

Does this make sense in the Docker environment? Shouldn't we be using env vars there?

Is this line longer than 80 chars? Can it be avoided?

I will make this code be run only in dev mode, so it won't be run in Docker, since Docker keyserver is always prod.

For some reason eslint/prettier doesn't allow

const keyserverAuthoritativeKeyserverFile = 
    `${keyserverFactsFolder}/${authoritativeKeyserverFile}`;

but also doesn't really tell why

I think it would be good to make it more clear that this only affects dev here. It would also be good to make it clear what config is being generated.

Two potential suggestions:

1. Rename to createAuthoritativeKeyserverConfigFilesOnDev
2. Rename to createAuthoritativeKeyserverConfigFiles and lift the process.env.NODE_ENV !== 'development' check to here
