As liferay 6.1 RC is released, i thought of giving it a quick try. Here are the new steps you will notice once you install and start the tomcat beside the regular installation steps mentioned in this article Quick Installation Instructions.
1) Configuration Screen
This screen will give you few options to configure the portal, before it deploys all the Plugins.
2) Once you click Finish Configuration, It will deploy Additional Plugins. You will see this intermediary screen.
3) Reset Administrator Password
Portal will ask you to reset the default password of firstname.lastname@example.org user.
