Oh, that's indeed interesting! What command were you using exactly to do 
so? My tries failed when it came to booting the new USB key, as it 
didn't copy the syslinux folder.

Yes, you can. But the script I wrote above (which calls 
livecd-iso-to-disk, btw) doesn't set an overlay by default; mostly, 
because I don't know yet, what reactions this would cause when it comes 
to duplicating another USB key.

So the use case I was describing is: Boot an existing USB key. Plug in 
another one. Call a specific tool and have it copy the system over. 
Reboot. One might then use the second USB key, too.
