Eelco Dolstra 724b7f4fb6 Don't log from inside the logger
This deadlocks ProgressBar, e.g.

  # nix run --impure --no-substitute --store '/tmp/nix2?store=/foo' --expr 'derivation { builder = /nix/store/zi90rxslsm4mlr46l2xws1rm94g7pk8p-busybox-1.31.1-x86_64-unknown-linux-musl/bin/busybox; }'

leads to

$ curl -L https://nixos.org/nix/install | sh

Information on additional installation methods is available on the Nix download page.

Building And Developing

See our Hacking guide in our manual for instruction on how to build nix from source with nix-build or how to get a development environment.
