UDS (Ubuntu Developer Summit) for Karmic Koala took place this year, between the 25th and 29th of May, in Barcelona, Spain. There were 270 blueprints that needed to be discussed during the summit, like the new professional look of Plymouth (an application that takes care of the graphical boot animation) for Karmic Koala, which will not become reality very soon.
However, some of the ideas discussed at UDS will be implemented in the next version of the Ubuntu operating system, due for release in late October 2009. One of these was the "grub2-as-default" discussion, and Colin Watson had the pleasure to announce last night that GRUB 2 would definitely be the default boot loader in Ubuntu 9.10.
