Gentoo ---> Fedora Core 4 what am I doing....

So I am moving my main workstation from beloved Gentoo to Fedora Core 4. Why? I am not sure. I have a need to get in touch with my Red Hat skills again and grok my RPM KungFoo to its fullness. RPM skill is something that is hard fought. Gentoo is still on the laptop though as it is too slow to run something as behemoth as FC4.
Yum and Apt are the only way to go in this sit...so here is the
"for i in /etc/apt/sources.list.d/*;do cat $i;done"
rpm http://apt.sw.be/ fedora/4/en/i386 dag
