Review comment:
We can put a unique prefix for helping avoid possible conflict but I think
still a rule of thumb is that users need to be cautious in choosing mounting
directory name. In case of this new option, the base directory is fixed to /tmp
so conflicts might not easily happen.
For multiple mount dirs, I'm not sure how much it's useful since users can
create as many directories as they want in a single mounting directory.
