I used the wrong /config path
* Note: NEVER use /mnt/user/appdata/APP_NAME as the host path for the /config files. The FUSE md driver does not properly support symlinks which most Docker applications require (many documented instances of this around the threads). Always reference your appdata via /mnt/cache/appdata/APP_NAME If you do not have a cache drive, and are storing your appdata files within the array, then reference the appdata like this: /mnt/disk1/appdata/APP_NAME (or disk2, disk3, etc) If you dont do this, you may run into unexpected results with your applications -> not starting up, strange results, etc.
