[knot-dns-users] Disable journals

Hello, I want to use Knot for master zones only without any DNS updates, so journal files are not needed. But they are created for every zone and it seems impossible to disable them. But this is bad in my situation when I want to serve 200000+ zones, because it creates 200000+ journal files in one directory (but they are never used). Should be possible to disable journal files or create them only in case of need or at lease divide them into more subdirectories? It would be also nice to be able to choose another directory for journal files in configuration. "storage" option is for both (zone files and journal files). Or explicitly state journal file path and filename in "zone" section. Thanks Petr Šťastný
