One of the features of Solaris 10 which is no less important than DTrace, Zones, and SMF is the re-write and major speed-up of the network stack. Internally the project is called FireEngine, and BigAdmin carries an interesting round-up of this new stack.


OpenSolaris BrandZ is a framework that extends the Solaris Zones infrastructure to create Branded Zones, which are zones that contain non-native operating environments. Nils Nieuwejaar has a blog post where he installs a Debian zone with BrandZ.
