Hi,

I just tested/played with this a bit and couldn't find any issues within 
the container, with the option enabled.

However, you need to add a corresponding mount option in the GUI, as 
otherwise, the "Edit: Mount Point" window breaks due to it not 
recognizing the option, and no changes can be made as a result.
