Two rpm packaging things I did not know until now.

Sure, there is lots I don't know, but here are the two latest things.  Also, I'm talking about spec files and the creation of rpm packages with rpmbuild.

1. You can have a verify scriptlet. I never knew that until messing with repackaging Sun's JDK 6.
2. You can specify what tests to run on files during an rpm --verify operation.

While #1 is interesting, I could have really used #2 on a recent project.
