The reason why I say the above is because a Live ISO, when DD'd to the
internal hard disk, prevents the permanent messing of system components,
because of the fact that it's Read Only. If someone wants to use a computer
with the Live Image as the hard disk, they will have to save their data onto
a flash drive. If someone does "try" to mess with the system, it can easily
be booted back fresh.
How this can be done involves booting from the live DVD, opening a terminal,
and typing:
sudo dd if=/dev/sr0 of=/dev/sda [status=progress]
And then once you eject the DVD and reboot the system, the same interface
will pop up and you have to select "Try Trisquel Without Installing".
