Notes on Release, Build and CI Engineering
In this article we address another topic which appeared in multiple discussions recently. We take a look at the difference between the SRPM and the so called dist-git repository of a package. And why do we indeed prefer the dist-git.
I know people who imagine distribution development as the process of piling up the code in the git repository for 6 months and then building it all in one go at the end of those 6 months, so that it can finally be shipped. This is very far from reality. And it is impossible to explain things like CentOS Stream without addressing this confusion.
The Ultimate Source of Truth, Wikipedia, defines continuous integration as the practice of merging all developer working copies to a shared mainline several times a day.
My version goes a bit deeper.

The chase for “bug-to-bug compatibility” hurts community, hurts RHEL customers and hurts the industry as a whole. The real innovation behind the CentOS Stream is the attempt to change it.
