Thanks but he wants to build "our" SL RPMs. After some more back-and-forth with him, I understand the question better: (Not that I like it much better.) If someone wanted to rebuild an existing RPM (the one that was used in the example was "perl") *exactly* the same way it is done for the current SL release process, how would it be done? The objective being, *if* they needed to, how could they reproduce an existing RPM release using the SRPMS including all the same configuration arguments? I'll phrase it this way, if someone wanted to set up their own building environment for SL, where's it documented? I'm sure I've seen it before but I can't find it.
