I think that development process has changed: now there is no constant system updates, as like in times of 2008.5 till 2008.11. Now there are several repositories (like in Debian - hi Jan Murdock!), which are smth. like stable, testing instable. You can take a look into front page of opensolaris.org, there are pyramid showing current scheme of development process.
So, you either should use this new repositories (though I don`t yet know how), or wait till 2009.5 This is how I is see things. -- This message posted from opensolaris.org
