This problem is the case where you just want to rebrand, not including 
other packages or doing anything non-Fedora. For example, live spins 
that have not been approved by the Board yet, will want to:

%packages
-fedora-logos
+generic-logos
%end

and the machine booting the live media would still show "Welcome to 
Fedora". Can one safely do:

%post
sed -i -e "s/Fedora/Generic/g" /etc/fedora-release
%end

?
