If you ever went to a cyber cafe, you probably noticed that any changes you make to their system: create or delete files, settings and so on, everything resets when you restart the computer. That's what the Deep Freeze program does.
Ofris is a Deep Freeze like application for Linux that is very easy to use - once you install it, you can "deep freeze" your Linux computer in a matter of seconds.
Ofris comes with an Ubuntu PPA so you can install it using the following commands (available for Ubuntu 9.10, 10.04 and 10.10):
sudo add-apt-repository ppa:tldm217/tahutek.net
sudo apt-get update
sudo apt-get install ofris-enThe last command will install the English version of Ofris (the package called just "ofris" will install the Indonesian version).
Once you install it, open a terminal and run:
ofris-enAnd then select what you want to do, like freeze the system for this user or for another user. You can later unfreeze the system the same way.
