[IAEP] Introduction: teacher interested in SOAS

[Thomas Gilliard]

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)

Look at this tutorial:
  http://wiki.sugarlabs.org/go/Tutorials/Installation/Install_with_liveinst

Other sugar related tutorials are located here:

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
