I guess you know that most of the changed parts were generated from default.upstream? @7c6f434c should know more about it.

[wkennington]

Yeah, I'm aware but not really sure how I feel about it :/. We probably need to discuss that style of automatic updating and packaging.

[codyopel]

I suppose, but I haven't been able to completely figure out how update-walker.sh is supposed to be called and not many build make use of it.

I've never used it myself; I just know it exists. A few other people also have their own generic updater scripts, and there's also nixpkgs monitor.

Perhaps one day we might agree on a common metadata format for these to unify what's committed into nixpkgs, i.e. standardize format that specifies how to determine whether an update is available, e.g. skipping unstable/testing updates and verifying crypto-signatures. Then we could have reliable automatic update detection for important packages.
