Hi, I tried to match what is installed on a system with what is available at git.centos.org.

for example

... [centos-release] $ ../../centos-git-common/show_possible_srpms.sh centos-release-7-0.1406.el7.centos.2.3.src.rpm [centos-release]$ rpm -q centos-release centos-release-7-0.1406.el7.centos.2.4.x86_64 [centos-release]$ rpm -q --qf '%{SOURCERPM}\n' centos-release centos-release-7-0.1406.el7.centos.2.4.src.rpm ...

So centos-release-7-0.1406.el7.centos.2.4.src.rpm is not in git!

Here are all my non matches from quite a minimal system name installed-version latest-in-git

CentOS handles the DIST tag as it always has ... if we make changes, there will be an .el7.centos. If we rebuild the upstream code exactly, then we will use their dist tag exactly. (If this is your question).

Since all DIST tags are dynamic (and the reason for that is because sometimes Red Hat uses .el7 .. sometimes they use .el7_0, .el7_1, etc). Red Hat also does not hard code the DIST tag it is put in at build time as a variable, but not in the SPEC.

So, the dist tag can be whatever you want, it is dynamic, and passed in at the time of build (but not hard coded in the SPEC). That is how Red Hat releases SPECs. If XYZ linux wanted to make every DIST tag be .el7.xyz then they can do that at build time by setting it inside their rpmmacros at build time.

Red Hat used .el7 for packages in their 7.0 QA release, they use .el7_0 for most updates between 7.0 and 7.1 ... but they use .el7 for FasTrac builds. They might, at times, use .el7 for updates (for example, the kernel).

So because of this, we will use dynamic DIST tags.
