ah, ok, I get it now!

so basically I should set up one computer with everything I want
*both* to have, then move the "overlay" onto the ltsp  /i386 folder
and recreate the image for the machines to boot off. Then each will by
default have their own settings via the overlay thing. To quote a
popular commercial, "Genius!".

Thanks for clearing this all up for me!
