# NixOS from scratch
My attempt to bootstrap a build environment in nix.
```
nix build -f busybox.nix busybox
```
All the busybox commands get exposed in a derivation called `utils`.
You can build it:
```
nix build -f busybox.nix utils
```
The output of the derivation can be used as part of a `PATH` in a shell like it is done in `shellDerivation`.
