What happened to the options I remember seeing in screenshots where you can select install and shutdown? That way I can leave my computer while things are installing... and come back to my computer to find it finished and not turned on. As far as I'm seeing, you have to hit install, type in your password, wait for it to download, type in your password again to install the download, wait for it to install, and then hit shutdown when the install is finished. This seems absolutely silly to me. Am I missing something?
