slipstreaming SP1 & Vista

[strangequark]

Now that it's getting close to the release of the final of SP1 for Vista I thought I'd check to see if you can slipstream SP1 into Vista to create a new SP1 install disc, to see if it was going to be the same procedure as with XP or if there were any changes. I immediately ran into a bit of confusion out there on the net, some sites were saying you could but a good number of sites were saying this can't be done expect by a method called "Reverse Integration", which sounds like a very long winded way to make a new disc.
Does anybody know the truth on this, I suspect no one tried with the SP1 betas, one place I visited reckons M$ will have it sorted by SP2 ..... maybe.
I love it when people turn something simple into a something complicated
