There was a problem hiding this comment.
This should be experimental at least as long as the underlying nix features as stable, but by that token, the barrier to merge should not be too high.
We're backporting this because want to use it in the preexisting test for this in the Nix repo --- that test is currently handrolling it downstream. Having it dogfooded upstream will make it more robust.

Things done
Upstream Nix recently added support for the features required to run an unprivileged nix. This PR adds support and a basic test for running nix unprivileged with full sandboxing.
This new configuration is based off those used in its VM test. If I have implemented this correctly there should be no actual nix changes if the daemon is running as root.
