| 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 |
