So, I did try to kick off a discussion of this before, but the thread kinda petered out. So we discussed it at the QA meeting this morning, and we decided to just go ahead and move the final F15 GNOME 3 Test Day to 2011-04-21, from its current place at 2011-04-07. 2011-04-07 is very close to the scheduled date of GNOME 3 release, which would leave us with the same problem we had for the first two test days - struggling to get a big new package set landed and live images built. Moving it to the 21st should make everything a lot smoother. Given the total two week delay to the F15 schedule that we're working with currently, the final change deadline for F15 is 2011-05-09; at 2011-04-21 we won't even be at TC1 stage for Final, so it should be plenty of time to get any bug fixes in that the event exposes the need for.
Of course, we can still change this again if it's a big problem for anyone, so please let me know if 2011-04-21 is a terrible date and we should change it. But otherwise...that's when it's going to be :). Thanks everyone!
