The Linux Schools Project
Karoshi is a free and open source school server operating system developed by the Linux Schools project and based on Ubuntu. Karoshi provides a simple graphical interface that allows for quick installation, setup and maintenance of a network.

The Linux Schools Project (formerly Karoshi, which can be translated literally as "death from overwork" in Japanese) is an operating system designed for schools. It is a Linux distribution based on Ubuntu (operating system). The project maintains two custom distributions, with one designed for use on servers and the other for use with the server version on client machines. The server distribution is the official Karoshi, while the client is known as Karoshi Client.
TLSP uses prepackaged GUI scripts in order to simplify the install and configuration process for inexperienced users.

History
TLSP was originally developed using Red Hat, early in the 2000s, with the aim of making Linux adoption easier for schools in the UK. Linux, at the time, was considered difficult to use in educational environments where computing expertise mainly came from teachers who were not dedicated IT staff.
With version 5.1.x, TLSP moved to the PCLinuxOS platform - but has since adopted Ubuntu in its place. The current production version of TLSP is 12.1.

Features
The installation steps require an initial install of Ubuntu, which the Live CD prompts to initiate. Following the machine reboot after installation of Ubuntu, the install of the TLSP system is initiated automatically.
