I was using the drivepool as a store for docker (yes, running in WSL2). A 'dir' from windows (using a normal NTFS drive) shows it as a 'junction (J)'. And the 'junction' tool shows "UNKNOWN MICROSOFT REPARSE POINT". I can dig into the tool ("certbot") (possibly)... but it works on a normal drive and not drivepool. It's a show-stopper.
