 emily | * uh, yeah, I was thinking about how to search in the unique hashes column and completely blanked out the first one :) | 18:06:25 |
| emily | https://git.netfilter.org/nftables/commit/?id=64c07e38f0494093a399a68a31056f5866c4d705 is wild | 18:07:31 |
| emily | introducing an in-binary build timestamp in 2025? really? | 18:07:38 |
| emily | with no override? | 18:07:54 |

 raboof | * New Graphical ISO runtime report populated: https://reproducibility.nixos.social/evaluations/2/fb7944c166a3 - ~10~ 11 unreproducible derivations remaining (all with GitHub issues) | 09:30:07 |

| raboof | together with abacef we populated another 'graphical iso build closure' report, https://reproducibility.nixos.social/evaluations/5/e4bae1bd10c9 . The majority of issues are instances of https://github.com/NixOS/nixpkgs/issues/151347 . I enabled -fobject-determinism for ghc 9.12 in https://github.com/NixOS/nixpkgs/pull/481942 - that should solve most of these once nixpkgs makes the switch from ghc 9.10 to 9.12 | 13:18:31 |
 Julien | Very happy that we have a new contributor for the hashes! | 13:39:27 |
|  Moved to: @astro:c3d2.de changed their display name from Astro to Moved to: @astro:c3d2.de. | 21:38:46 |
 abacef | Just wondering, how does nixpkgs decide to increment their ghc version? | 21:58:53 |
| raboof | We follow stackage LTS https://nixos.org/manual/nixpkgs/stable/#ghc-deprecation-policy | 22:03:50 |
| raboof | Squinting at past ghc and stackage release dates it looks like stackage LTS being released with ghc 9.12 will still be some months away, but I haven't followed closely | 22:13:34 |
| raboof | So not for 26.05 but probably for 26.11 I'd wager | 22:18:21 |

| abacef | What do yall think about verifying nixos arm reproducibility? | 23:49:46 |
| 24 Jan 2026 |
 dish [Fox/It/She] | its definitely a good idea | 00:23:34 |
| dish [Fox/It/She] | but would there necessarily be differences w.r.t. x86 there? Are there any cases you've found where ARM is reproducible and x86 isn't, or vice versa? | 00:24:12 |
| abacef | Debian packages have differences per architecture https://reproduce.debian.net/ | 01:28:01 |
| Julien | Would be good im | 12:23:25 |
| Julien | * | 12:23:29 |
| raboof | sounds like a good idea to do, shall I define a graphical-iso-runtime-aarch64 jobset? | 12:29:25 |
| Julien | Does anyone have hardware to verify it ? | 14:44:46 |
| raboof | I have a pi5 that I could put to use (though it'll probably be slow and fail on some of the larger builds). I still need to finish/troubleshoot setting it up though - for some reason it seems the async-nix-post-build-hook is hanging. | 16:54:21 |

| abacef | I have some Azure credit I can get an arm server | 20:03:50 |

 Atemu | Never tried it but oracle has a free tier that includes an ARM VM with 24GB | 00:32:24 |
| abacef | I try to get free Oracle ARM VMs with my account sometimes but every time it says they dont have capacity in the single region where my free account is locked into. | 10:39:34 |
