I've been going thru latest heads-ups for Nevada and found this. In the past we had Trusted Systems which were entirely separate system installs. Then with Trusted Extensions in Solaris 10U3 you could get a Trusted System by just installing your software. Now all is required is a one command... I'm a little bit oversimplifying here of course but still looks like we're getting Trusted Systems features being more and more part of a standard operating system.
