You can assign the datafiles and dump files to any location you want via the spfile settings and the file names you code into your CREATE DATABASE script.
We place all our datafiles and dump files outside the Oracle binary directory structure so we can upgrade by creating totally new Oracle Homes and just start Oracle using the new home. (The init.ora/spfile being one file we copy)
Modifying the version 9 and 10 scripts to use identical structures if desired is a trivial task.
