| 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 |

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 |

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? I don't think I ever got around to actually successfully reproducing end-to-end, but AFAIK we did fix all the problems I found when I tried it the last time. Indeed r13y does not automate everything (but quite a lot). | 08:18:35 |

A similar situation I ran into was when I was testing out CA, several URLs were broken because our caching kept it longer than upstream did | 00:56:10 |

| baloo | Nix2.5.1 merged in master. So the man build for nix should be fixed soon | 21:06:31 |
| Rick (Mindavi) | I made an issue about an interaction between separateDebugInfo and ca-derivations: https://github.com/NixOS/nixpkgs/issues/151475 | 22:53:33 |
| Rick (Mindavi) | I think it would be really nice to solve that issue to be able to really get consistent ca-derivations working, reducing the influence of the input-addressed path on the derivations. | 22:54:15 |

| Rick (Mindavi) | I guess it is a symptom of how the build process works, but it may be worth 'generating' the build ID based on a hash of the source contents, or something like it.
This could also be fixed on the nix side by using a non-input-addressed but deterministic folder name for the 'scratch space' build folder, which doesn't depend on the derivation or it dependents. But that seems a lot more intrusive and it's of no value for normal non-ca builds | 07:43:49 |
