FreeBoo: an Open Architecture for Network Dual Boot
The BP Batch Project, started at the Geneve University by Marc V. Stuckelberg and David Clerc, became a popular open implementation of the thin client. This approach evolved into the commercial Rembo suite, which is used in many labs with a significant licensing cost. FreeBoo uses a combination of existing open-source technologies, including BP Batch, to provide the main features of Rembo.
The hardware requirements for installing FreeBoo are just a dedicated server connected to client desktops by a LAN. Desktops need to have only boot-on-LAN capacities and local disk drives. All the software used is open source.
Future extensions of FreeBoo include the use of this technology for server software deployment; the development of a Web-based interface for easy administration of images, including database management; evaluation of the performance of the OS restoration process to improve it and to select the best option automatically (instead of having the user decide between the fast or full options); the insertion of multicast image recovery; and finally, the use of Wake-on-LAN capabilities to deploy secure images to desktops at preprogrammed times.
FreeBoo is only the initial step in building an open-source boot environment for system administrators that allows you to fix, deploy and execute OS images on large installations of desktops.
The scripts and other files related to FreeBoo can be found at ftp.linuxjournal.com/pub/lj/listings/issue180/10203.tgz.
