Using the Dev Repository with Trusted Extensions

Now that OpenSolaris 2009.06 has been released, the next major release is planned for 2010.02. You can get early access to it by pointing the Package Manager at the Development repository. Since the 2009.06 release, based on build 111, there have already been some major changes. The latest OpenSolaris build number in the Dev repository is 121, and updates occur about every two weeks. This release includes some changes to the labeled zone brand. A new meta-package called trusted-nonglobal specifies the minimal set of packages needed to run the Trusted Desktop in a labeled zone. This is now installed automatically via the txzonemgr. While this is referred to as a whole-root zone, it should not be confused with the way that term is used in Solaris 10. Previously, a whole-root zone contained a copy of all the packages that have been installed in the global zone. But a whole-root labeled zone is a minimized install. The list of packages in the labeled zone brand is enumerated in this manifest. Other differences in the configuration of labeled brand zones have been factored out of the template file and made part of the brand specification. This makes it easier to make future changes transparent to the administrator.

The latest version of GNOME is 2.26.2. This fixes some previous problems like the Trusted Stripe occasionally crashing. But there are still a few required workarounds. These should be fixed in the next major GNOME version, 2.28, which is scheduled for OpenSolaris build 124.

I've added a link to the Trusted Extensions page on OpenSolaris which describes how to install and configure Trusted Extensions using the latest version from the development repository.
