Or, you could use NixOS and just declare your systems in some text files, git commit; git push.

You build script becomes:

   while true; do

   git pull

   nixos-rebuild switch

   sleep x

   done

That's it. You can even do it remotely and push the new desired state to remote machines (and still build on the target machine, no cross compile required).

I've completely removed Ansible as a result and no more python version mismatches, no more hunting endless task yaml syntax, no more "my god ansible is slow" deplyments.
