 That's even worse.  The user has no way to know if or when the overlay
 will run out and the SoaS will die, with all data lost (unless a school
 server has a back-up).  I see this as a very serious problem that merits
 community attention.  Is there a discussion on the wiki?  If not, I'll
 happily create one.  Where should it go?

 > It already
 [http://wiki.sugarlabs.org/go/Category:Live_USB#Cautions_with_using_Live_USB.27s
 does], but I agree it's not clear enough. If you have some time, it would
 be nice if you could improve those warnings.
 Done.

 > Bernie has
 [http://lists.sugarlabs.org/archive/soas/2010-January/000654.html manually
 installed] a SoaS image directly on a USB stick, without using the size
 reducing hacks, thereby eliminating the issue. Unfortunately none of the
 tools seem to support this installation method, though.
 Considering how inexpensive larger USB sticks are, this seems to be the
 easiest and best solution, and worthy of more efforts.
