Hi

Just to add my 2 cents to this threat:

What about using rpm-macros?

I know SUSE has the macro %suse_version which is set to the current SUSE
version like 1020 (openSUSE 10.2).
With that, you can just make something like this in your specfile:

%if 0%{?suse_version} > 1020
do_this
%else
do_that
%endif

If you don't need the "> 1020" just leave it out. If the macro is not
present, it will expand to "0" and so RPM jumps in the %else tree (if you
have one). I'm doing this already with some RPMs in the openSUSE
buildservice [1]. I don't know if other distributions like Fedora or
Mandriva have these macros defined on their real plattforms (a look into
/usr/lib/rpm/*macros* should help), but with this you can do thinks like:
%if 0%{?mandriva_version}
...
%endif
%if 0%{?fedora_version}
...
%endif

This makes writing specfiles not really easier, but hopefully in some
future time we always just use one specfile for all... Other projects
have a directory "distribution" which contains specfiles for each version
and distribution sorted in subdirectories in it.

Lars
