I want to install a ubuntu SO on some laptops. This laptops will be used for studens between 12-16 years old, so to avoid problems I would like to start the ubuntu every time from a clear .iso (like in a USB live). In other words thats it that everithing that the studens do won't be saved in the machine. At the same time I need to save some configurations and add some repositoris for the use in this iso (wifi configuration, some programs...). Someone knows if that is possible?
Thankyou
