Lethe is a Deep Freeze -like partition freezing software for Debian GNU/Linux and Lihuen GNU/Linux (May work on other Debian-based GNU/Linux distributions). Lethe makes the partitions behave like a Live CD: all changes made on the file system will not be saved on the disk but in RAM and when the system restarts, all the content saved in the previous session is "forgotten" and lost and the disk / partitions are restored to their original state.
The project is no longer developed. Last version, 0.34, released in January 2011, can be still downloaded from SourceForge
