Hi there, Many thanks for the response. I ended up finding the solution: It works if I set the mount target to be any folder in the Home directory, so long as the folder is not inside one of the default folders (Eg. Documents, Desktop, Downloads, etc.) So these work: mount -t passthrough ~/Documents ~/test mount -t passthrough ~/Downloads ~/test/best But these will not work: mount -t passthrough ~/Documents ~/Desktop/test mount -t passthrough ~/Documents ~/Downloads/test I tried these after restarting my computer too, so I don't know whether restarting had an effect or not. In the sample project guide, each time the mount target is mentioned it is prefixed with "For example...", so I assumed I could use a target located elsewhere like in ~/Desktop Regards,
