How to obtain latest slipstreamed installation media for OS X? I'm looking for a way to obtain an updated installation media for OS X 10.6.x, currently 10.6.6

I am looking for a similar solution to the Windows slipstreamed installation media and preferably a solution to put the kit on a USB drive in order to improve the installation speed.

Is this possible, and if it is how it is possible to get such a media?
Same Answer as given here:

Basically you want to use the System Image Utility to create a bootable .dmg you can than put on a USB drive.
Have a look at this post, it covers this process in detail (you probably can leave out some steps); this should get you started.
