RPM macro set hell

It's fortunate if typical one loaded with mammoth's stdout like BuildRoot and %clean actually builds on say Fedora *and* openSUSE but ask packagers on RPMs with better macro set and they'll yell "CRAP!" at that.

I'm not even touching surface with stuff like control(8) which is developed and supported in Owl GNU/*/Linux and ALT Linux to let the packager limit the SUID/SGID scatter, and to let the sysadmin set up app modes in persistent manner. How can I propose to add %pre/%post scriptlets supporting that to upstream if that would blow up on mainstream cr... distros, that is?

Disclaimer: I maintain some 200+ packages in ALT Linux, most of my spec imports begin with "{,massive }spec cleanup" in %changelog (if there was any) and Fedora specs are usually last resort being usually, well, ugly :(

While at it, I'd not recommend Mandriva to anyone since "new order" fired Gael. Well, some people chose to work with them or use what they do; hope they understand before too long. Sad since there was nice feeling with a touch for details there... back in 7.x days.
