Well, you clearly have a different idea of what a "live usb" system is than I 
do.  I expected it to be something that could be booted repeatedly and have the 
exact same environment each time (i.e. no changes allowed to the usb storage), 
while you seem to be talking about just a normal install on a usb stick.

How the image is created seems to me like something that is not at all relevant 
to how it is used, and I imagine that 99% of the time will be people *using* a 
pre-made image, not creating their own.  The times that I've used livecd images 
the grab-it-and-go feature has been the biggest reason for using it, so I don't 
care what steps might have been needed to create it.
