I use the "liveinst" command (fedora anaconda installer) in sugar root
terminal [# ] to install to a 4 GB USB (with a led activity indicator)
Teach the students to wait for the flashes to stop before removing them.
These USB can be very cheap (I purchased some EMTEC 4GB for $9.95 recently)

This installs a real file system to the Soas USB. This is a much more
robust form of SoaS Stick.
It does not rely on a frangible persistence file
