Well, not really. There is this. But we are not using any of them, so no problem. But there are tools like imagex, WINRE (Windows Recovery Environment) and others that have new SP1 version, even WinPE.
Hah, lucky dash. I'm anxiously awaiting SP1 and wasn't a lucky glitch person. Oh well, another month won't kill me..... I hope ;P
Hehe.. IMHO, wait it out. It's already final, so you know it's just a matter of a few weeks before it's released publicly. Let Microsoft test the delivery first. If I'm not mistaken, they have just noted some problems with the installation process, where some people have been locked into an endless loop of reboots.
