The Nix daemon needs to have NIX_REMOTE unset, or it'll loop infinitely

[MagicRB]

In the nix module the environment variable NIX_REMOTE is set globally to daemon, which means that when running under dinit which properly inherits environment variables, the Nix daemon process itself will be running with NIX_REMOTE=daemon which causes an infinite loop of the daemon trying to connect to itself. The environment variable needs to be unset, such as below:

  export NIX_DAEMON=

or even better

  unset NIX_DAEMON

though I haven't tested the second one yet.

To reproduce make a container with dinit and nix.enable = true, nix.daemon = true then run the following commandS

  nix-build '<nixpkgs>' -A hello
