For those who don't know, Nix[0][1] is a package manager that allows you to specify exactly:
- the build environment
- the dependencies
- and the steps of the build
This translates into 2 main benefits: - if you made the build run now, it will run in the future (reproducibility) - it reduces bloat, because you can generate an environment or OS image with only the software needed to run a specific program or service
My guess is that a big efficiency gain would come from the second point, because you don't waste CPU on code that you don't use.
Does this make sense? Has anyone explored this?
