| gluonix | Hi, trying to understand why building a flake in a docker container yields a different binary than when building with nix on host machine. | 05:24:33 |

| gluonix | What variable controls the build directory when using nix build? | 00:01:57 |

What variable controls the build directory when using nix build? https://nix.dev/manual/nix/2.24/language/derivations.html#builder-execution | 00:42:05 |
| Artturin | And source is unpacked to sourceRoot and then cd to it for the rest of the build https://github.com/NixOS/nixpkgs/blob/54830391487253422f0ccab55fc557b2e725ace0/pkgs/stdenv/generic/setup.sh#L1712 | 00:42:37 |

| gluonix | thanks | 00:43:07 |
| gluonix | I am trying to figure out how to obtain the same bit-for-bit builds inside a docker container, compared to outside, just with nix build | 00:43:55 |
| gluonix | from running diffoscope, one thing that stands out is the different build paths | 00:44:30 |
| gluonix | For instance, without docker:
/build/cargo-vendor-dir/...`
versus, with docker:
/tmp/nix-build-teleport.drv-0/cargo-vendor-dir/...
| 00:46:27 |

| Artturin | Definition is a few lines up | 00:48:25 |
| Artturin | You can enable sandboxing https://hub.docker.com/r/nixos/nix shows how | 00:49:33 |
| gluonix | yes, ok, I was reading about this | 00:49:51 |
| gluonix | This applies to the docker-nixpkgs images as well right? I am using nix flakes so the image nix-flakes or cachix-flakes is convenient. | 00:50:34 |

This applies to the docker-nixpkgs images as well right? I am using nix flakes so the image nix-flakes or cachix-flakes is convenient. Should work in any docker with nix | 00:51:06 |
