The Determinate Nix Installer

The Determinate Nix Installer is an opinionated alternative to the official Nix install scripts.

curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install

The current Nix install scripts do an excellent job. However, they are challenging to maintain. The team at Determinate Systems wishes to experiment with the idea of an installer in a more structured language and see if this is a worthwhile alternative. Along the way, we are also exploring a few other ideas, such as:

offering users a chance to review an accurate, calculated install plan
having ‘planners’ which can create appropriate install plans
keeping an installation receipt for uninstallation
offering users with a failing install the chance to do a best-effort revert doing whatever tasks we can in parallel

So far, our explorations have been quite fruitful, so we wanted to share.
