Have you actually updated an OS X install before, or are you just basing it on the crazy Windows update experience?

Apple distributes combo updates that will take you straight from a base 10.6 install to 10.6.7. You don't play the goofy multiple-version update game.

The occasional security release breaks that. I have had to install updates, and then it found more after a reboot. Though I haven't done that on a base 10.6 to current.
