Hmm, it doesn't seem like %{rhel}, %{rhl}, %{el#} are set on CentOS. I
tried adding an echo <var> to my .spec file for each and they all show
up empty.
Actually, just tried on a real RHEL5 box and
echo %{?rhel}
Is empty as well. And, when I set up an if block using this:
%if 0%{?rhel} == 4
stuff
%endif
"stuff" never is executed.
Guess I will rely on %{dist} for now.
