[luau] thumb drive

As another side point (as everyone can see, I am quite excited about the 
use of USB storage in Linux), I typically don't mask the entire /home 
directory, rather, only my user directory, i.e., /home/xxxxx.

Of course, before you do that, the root of the host machine must create 
the same user for you.  After all, this is not Windows, and you have 
show respects to the host machine.
