> I found this warning confusing as it is always logged when relying on the
> default configuration (via {{WebOptions}}) that picks a random directory.
> Ideally, our default configurations should not result in warnings to be
> logged.
> Therefore, I propose to log the creation of the web directory on {{INFO}}
> instead of the warning.
