 baloo | and get a release cut | 13:28:23 |
| baloo | I don't get the unchecked paths for pcre2 | 13:41:46 |
| 30 Nov 2021 |
| baloo | oh well, the pcre2 got fixed | 10:19:10 |
| baloo | thanks for the fix on nix tomberek | 10:29:11 |
| baloo | not too sure if we can just send patches in nixos or if we could maybe ask for a release cut (That would also include the dns fix I got last weekend) | 10:30:05 |

| baloo | tomberek: your fix for nix only fixes the core count, correct? | 13:51:43 |

| baloo | this does not fix the extraneous x86_64-v3-linux correct? | 13:52:24 |
| baloo | (not actually sure where that comes from) | 13:52:37 |
| baloo | this has to do with cpu support | 13:58:52 |

 j-k | should we even be recording the core count of the system that built the docs within the docs in the first place? | 14:01:00 |

| baloo | that's not the only problem | 14:17:13 |
| baloo | well, tomberek fixed the core one, but I count 3 problematic ones | 14:17:37 |
| baloo | cores, system features and platform | 14:18:06 |
| baloo | all 3 are dependent on builder's environment | 14:18:18 |
| baloo | I have a patch that selects the configuration settings where to filter out default values | 15:05:09 |
| baloo | (and I'm removing all 3 of those options) | 15:05:19 |
| baloo | there might be a better approach but I don't know | 15:05:48 |

| arcz | hey, I'm wondering if r13y is really verifying that NixOS image is reproducible. It seems that only the direct dependencies are rebuilt, not the whole tree down to some root bootstrap package, is that right? Is it possible to rebuild the whole tree, is it even worth it? | 16:33:55 |

hey, I'm wondering if r13y is really verifying that NixOS image is reproducible. It seems that only the direct dependencies are rebuilt, not the whole tree down to some root bootstrap package, is that right? Is it possible to rebuild the whole tree, is it even worth it? https://r13y.com/ doesn't check everything. One thing you could do is take an 'old' image, install Nix, download nixpkgs, disable cachix, and build the image. I have found a couple of issues like that in the past (e.g. around the way we used mksquashfs IIRC), but I'm not aware of any remaining. | 16:58:04 |
| arcz | raboof: not sure if I understood you correctly, so you tried to build everything from source and it reproduced, but it's not automated in r13y? | 17:09:50 |
