If you're having problems installing Oscam with this image and you haven't figured it out yet, you need to make a new folder in /var called tuxbox and then within tuxbox create the config folder, copy your oscam config then into that folder.
/var/tuxbox/config
^^ as above.
In general, the oscam config files are usually in /etc/tuxbox/config in other images but see what satinfo wrote in reply below to explain this better and why the DE team do it different (it makes sense!).
For others like myself who manually copy config files after installing a new image, what I've mentioned above will help you, otherwise follow the guidance from satinfo posted.
