Just remaster all of the ISOs. If they have to release May 1st, so what. They can still call it 10.04 LTS if they want to.
Of course, I can't even get the release candidate to boot live on my HTPC. I got a new HD and planned to do a clean install (dual boot, since I need Windows for the occasional bluray disc.) No matter what boot options I select, I get a kernel panic. It was late at night though, I probably missed something simple.
