Those instructions are ancient and outdated. I'd throw them out.  
Start with a Fedora kernel spec instead, and the Fedora custom kernel  
docs.

Yes. That's more or less what an rpm (and a deb) does, in a portable  
format.

Anything there that doesn't make sense, I'd love to hear about it,  
and can certainly try to provide clarification and any fixes to the  
spec as necessary.
