I have posted again and again example scripts that we use. We use mock to build packages ... specifically, we use the mock released in CentOS Extras for CentOS 5 to build packages. Some people keep asking for our mock config files. I gave examples of those (centos-5-i386-os-ft-extrasStaged.cfg, centos-5-x86_64-os-ft-extrasStaged.cfg). They are not rocket science. If you point to the [base] and [updates] directory for CentOS for the thing you are trying to build, then you have it. If you are building extras, add in [extras]. If you are building CentOSPlus, add in [centosplus]. If I provide you the exact file, it does not help. It points to names we do not want to give out because we do not want our internal names to published for security reasons, but we quite simply use [os] and [updates] to build the main OS, and other repos as necessary to build [extras] or [centosplus]. Point to ONLY the CentOS repos, we do not pull in any other items for our builds. If we need a package (in extras or centosplus) then we add it. We do staged builds (that means when we get a good build, it goes into the build tree). I gave examples of scripts that do that (cp_extrasStaged_live). We test the RPMs against upstream RPMs. I gave a script of that (tmverifyrpms). When we have a tree of RPMS, we build the "distro tree". I gave an example of that too. (build.sh.txt). All of the files I talked about in this post are either here: http://people.centos.org/hughesjr/buildsystem/ or here: http://mirror.centos.org/centos-4/4/build/distro/ Also included are actual buildscripts for an ExtrasStaged repo (buildpackages_mock_c5_extrasStaged_i386, buildpackages_mock_c5_extrasStaged_x86_64) and a script that "generates" the order to build packages based on their previous build date generaterpmlist(). All of this is also linked from here: http://wiki.centos.org/FAQ/General/RebuildReleaseProcess The point here is that we are not going to share access to our actual build system and we are not going to give you our actual build scripts off that system as they use names that we do not want to publish and contain files that we can not allow people to have access to. But these example scripts give someone who wants to build their own items the starting point that they need to do that. Thanks, Johnny Hughes
