Sun coughs up an OpenSolaris kernel - The Register
The Sun Microsystems OpenSolaris endurance test reached a critical stage today, as the operating system's kernel and networking stack were turned over to developers.
Solaris fans can now examine and play with more than 5m lines of code - mostly the stuff at the heart of the OS. This code dump follows the release in January of the highly-regarded DTrace tool for improving system performance under Sun's Common Development and Distribution License (CDDL). The new code, also released under the CDDL, is now available on the OpenSolaris web site.
