Update Manager

I was pleasantly surprised to see a new icon on my top panel today - the update notifier . Clicking on it opened the Update Manager, which you can also access from the System > Administration menu: Selecting Update All notified me that a new Boot Environment was going to be created. This is great as I don't have to worry about these updates somehow harming my system. The update took a couple of minutes to complete: After which I rebooted. There was a new opensolaris-1 grub...

Smiley face not 100% ready yet?

OpenSolaris 2008.11 has a new feature called graphical boot. We call it internally the "Smiley face".
