If you're interested in how Ubuntu gets installed on systems, want to ask about specific features, or have already filed bugs that you'd like to bring to our attention, watch for my session on the calendar:
http://summit.ubuntu.com/uos-1505/meeting/22512/core-1505-installer-healthcheck/
It's currently scheduled for Tuesday May 5th at 18:00 UTC (that's in a little bit more than 24 hours!); but just in case it changes time, make sure you're marked as attending and subscribed to the blueprint.
As stated in the blueprint summary, I can't guarantee we'll get to everything, but it will be the right place to see what has to be done, and for anyone to pitch in time if they're interested in helping out!
