Freeze your root (/) or any other partition of your choice. all changes happens in the RAM and all gone once a reboot process is completed successfully. good but not excellent for public libraries and internet cafes.This app doesn't have any features at the moment.
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...
The project is no longer developed. Last version, 0.34, released in January 2011, can be still downloaded from SourceForge
