I'd like to know if there is any alternative to Deep Freeze for Linux that still under development, because I've read some things on the internet and looks like the same company which developed Deep Freeze had a Linux version of it, but the project was discontinued.
OFRIS is an open source application that can freeze your Linux, it is like Deep Freeze in Microsoft Windows operating system.

By default Ubuntu and most other Unices deny regular users (students, guests) write access to system files. Only an administrator with the proper authorisation (username and key) can install software, change system settings, or delete partitions.
Regular users can, by default, only write in their home directory and the system's temporary directory. A common way to handle one-time guest sessions is to put their home directory inside the temp directory, and the temp directory in main memory.
If you want to make extra sure, mount the system partition read-only and lay an aufs partition over it that stores changes in main memory.
