alt Hacker NewsI've been wondering about the Red Hat model! Seems like so much of modern development involves git blame or whatever to make sense of how the code came to be, and sometimes rule out an "obvious" modification that actually turns out to be a bad idea now that you know the historical context.
GrapheneOS might have a better case though if it's not just about understanding the code but about how the Android build system expects that everything is in Git.
I don't know what "Red Hat model" you mean, but if you're referring to their code delivery: It's not a problem for their internal developers, because they can use git lol. You can theoretically go to the upstream projects individually and merge the code drop with their nearest branch, and THEN do git blame/diff to figure out the delta and history of some lines of code. There are probably a few upstream open-source projects out there with no public VCS, but those are rare.
