That you ndon't have much idea about what you are talking about.
RPM is just a packaging system, as mature as dpkg is. It has nothing to do with Fedora, since it was just RedHat in 1996.
deb and rpm are just a tar.gz or cpio.lzma archives with some installation helper scripts when needed, and a formated text package description, plus a database of some sort to keep track of files and packages, plus the tools to manage all of this.
And, by the way, I prefer rpm to dpkg. Just because I use it since 1997, and find it more robust than dpkg (find my posts about the last seamless update to diablo)
Please, stop whinning about the packaging system. They could have used plain tgz like slackware and it would make no difference.
