Here's a list of resources I've found for building Red Hat Package Manager (RPM) packages.
- Red Hat's book, Maximum RPM
- the IBM Developer Works article, Packaging software with RPM (Part 1) (Part 2)
- Chapter 8 from Eric Foster-Johnson's book, Red Hat RPM Guide
- Fedora Project's Packaging Guidelines
- Creating RPMs (PDF) lecture and exercise from Guru Labs
- Better Living Through RPM, Part 2, from Red Hat Magazine
