Thanks for posting what you did. I build test ones locally myself as well. It is quicker to build locally than on the GitHub runners, which can be slow. I don’t know why GitHub Actions are hated. Mine work fine. I have both builds using bluebuild (which take way longer to run but are easier to mana…

The reason I don’t like GitHub Actions is because the development loop is terrible.
