Wow, you have done so much work! Thank you so much. I am now adjusting all of these to point to meelgroup and the relevant branches.

don't forget to regenerate the lockfiles as well using nix flake update after modifying the branch names, if you add --commit-lock-file it will automatically create a commit as well

Ohhh so that's how it's done! I have always been just checking the error and copy-pasting the hash it calculated :D Thanks for that pro tip! Sorry, my nix/flake knowledge is pretty bad. Thanks, this helps a lot!

In the old version with the src = fetchFromGitHub that was indeed how you'd do that. But that's a thing flakes were made to improve the experience of in the first place since now the flake always has the source since it's in the same git repo. The dependencies just fetch a specific git commit and nix flake update updates those to the newest version.

I may decide in the future to use inputs.{name}.follows = {name} for more parts so running nix flake update on for example ganak will also update all the transitive dependencies instead of only the direct ones and the versions will be the same within the build itself
