I've been trying to mount an FSKit volume at the location where FileProvider saves files: ~/Library/CloudStorage . I've discovered that FileProvider attempts to call setAttributes in order to assign a value for an access control list (ACL). This call fails, because FSKit does not support this attribute, and causes FileProvider to stop working. FileProvider refuses to continue beyond creating it's domain folder when this occurs. Do you believe this constitutes a valid enhancement request for FSKit and/or FileProvider?
