How can i find files not controlled by rpm?

["Tom Hicks" <headhunter3 gmail com>]

I've built an LFS system and I've installed rpm.  I've created packages for almost everything I have installed.  Can anyone tell me an easy way to find all the files on the system that rpm does not control.

I want to create a set of rpms that I can install via rpm --root to install a complete system.

If there isn't an easy way I'll take a hard one too I just can't come up with anything else than installing them to another folder and doing a diff but I believe parsing through the diff output would be a bitch.

Thanks,
Tom
