Mac OS X and partitions


How will MacOS X differ from the way Mac OS 9.1 reorganized my file structure.

Specifically, I have my G4 partitioned into 3. One for System, one for Apps and one for capture.

Knowing that OS X will install in the root or System partition will it allow me to keep my directory structure of Applications on a separate partition or will it automatically load new installations into the Applications folder a la 9.1?

I sure hope now, by the way.
