From Kerrighed


Current Status

The current implementation of Kerrighed is based on a Linux 2.6.30 kernel. Kerrighed functionalities have been added to the Linux kernel through modules and some kernel modifications.

The version 1.0.2 of Kerrighed was the latest "pure research" version designed as a proof of concept of what we can do in Kerrighed. This version was quite well featured but not stable enough to be considered as a production quality product.

Since 2006 we are working at making Kerrighed strong enough to be used in a production environment. To do so, we have temporarily disabled some features to fasten the release of a stable version. Disabled features will be re-enabled in the next few months.
