Yes - I'm essentially just trying to /mnt to /mnt, which is what I think is suggested as the easiest (if not secure) way:

Do you understand volume mappings?
No, unfortunately - I've essentially just been following guides on these forums (e.g. http://lime-technology.com/forum/index.php?topic=37732.0)
Why do you have 2 mappings to /mnt?
Just trying random ideas - one is to /mnt and the other is to /mnt/user. Neither works, unfortunately (have tried it with just /mnt).
