Software Deployment

I'm trying to create an installation package for Oracle 9i client deployment to a Citrix server farm. I'm using their packager and their app deployment system, Installation Manager. I had tons of problems with the silent/custom installs of the Oracle client and ended up just using their clientadmin.rsp response file with some minor modifications. It installs more than what I'd like, but that's better than less or nothing at all! Anyway, I can run the install via command line from the server and it works fine. However, when I create a package for it using the Citrix Packager, it doesn't install correctly. It almost seems like the server reboots before the install is complete. Is there some way to suppress that reboot? Any other tips? I have read all the info. in the packages section and it was very helpful. Thanks.
