Hi Sam,

Whoever wrote the Ubuntu scripts did not really have Etoys users in  
mind :/

It's actually pretty simple. You only need the etoys image once,  
installed in some system directory. For OLPC we use /usr/share/etoys  
for example, but it doesn't really matter. What does matter however,  
is that you use a script to run etoys which sets SQUEAK_SECUREDIR and  
SQUEAK_USERDIR env vars to appropriate directories in the user's  
home. Here is one such script, feel free to adapt:

Btw, Kusasa is an awesome project! Feel free to join the Squeakland  
or Etoys lists for discussion of Squeak in education. Also, the  
version of Etoys we prepare for OLPC is much improved over the  
current Squeakland version, and will in fact replace that soonish.

Cheers!
