 raboof | * a new regression in the minimal iso runtime: why would something XXX out a self-reference in the RUNPATH? https://github.com/NixOS/nixpkgs/issues/458071 | 11:11:55 |

| Ron Kuris | Hey all, new here. We have an effort to use nix for reproducible builds but we're seeing some differences when we use jemalloc in rust. Does anyone know if this is a known problem and is there anything we can do about it? | 19:14:18 |
 @dawnofmidnight:catgirl.cloud | jemalloc has a couple known un-reproducibilities that should be fixed in nixpkgs, see https://github.com/NixOS/nixpkgs/pull/393724 for when some of those fixes were introduced. Using them in your Rust project should just be a matter of having rust-jemalloc-sys in your buildInputs. If you're having issues beyond that, no clue. | 19:27:33 |
| Ron Kuris | Yep, that lines right up. TYVM! | 19:37:02 |

 makefu | Very cool! It would be awesome to have the (latest) reproducibility numbers in percent directly next to the builders | 07:53:56 |
| raboof | Percentages are somewhat controversial, since we count 'derivations' rather than 'packages' which makes them not really comparable to what other distro's are reporting. | 07:57:59 |
| raboof | Redacted or Malformed Event | 09:32:57 |
| raboof | Julien Malka and Arnout Engelen launched the new hash collection
server for NixOS. Aside from improved reporting to help focus reproducible builds
efforts within NixOS, it collects build hashes as individually-signed attestations
from the builders, laying the groundwork for further tooling. | 09:42:51 |
