That sounds really neat is it some thing you can share? I recently setup a new machine which didn't take very long, but I have run into a few things I forget so would like to set up something similar.
To install, I run `git clone https:github.com/username/repo && ./repo/install.sh`, and I'm off to the races. I really reccommend writing one for yourself, as it's a great way to learn shell scripts.
For me there's a trade-off, depending on how often I setup a new machine. Value of automating with a procedural script vs taking the opportunity to try a leaner (or more modern) toolchain.
Currently upgrade about every 2-3 years, so I do tend not to need a bunch of things each iteration, and might upgrade OS. But I'd like a backup in case e.g. hardware failure, laptop lost or stolen.
Some declarative workstation config like terraform or Ansible would be interesting.
