 hexa | by which you mean … if Claude did the thing? 😜 | 14:37:24 |
| hexa | https://github.com/NixOS/nixos-channel-scripts/issues/59 | 14:38:00 |
| hexa | I'd like it if we had that | 14:38:04 |
 Mic92 | I did this once by hand for the nix release script back in the day but never upstreamed it. It had even a self-test with a local registry and minio. | 14:41:37 |
| hexa | so yeah, a job in nixpkgs that drops a manifest and we just upload what we just execute based on that | 14:42:27 |
| hexa | instead of piling on janky version dependent logic | 14:42:37 |

| hexa | Redacted or Malformed Event | 14:43:20 |
| hexa | and then, sure, it can be python for all I care | 14:43:32 |
| hexa | the code is so "complex" because we need to deal with nixpkgs changes | 14:44:09 |

| Mic92 | I am still in favour moving the iso image to a non-hydra CI. In nix we do that in GitHub actions with oidc Auth for aws | 14:44:32 |
| hexa | that's orthogonal, no? | 14:44:57 |
| Mic92 | * I am still in favour of moving the iso image to a non-hydra CI. In nix we do that in GitHub actions with oidc Auth for aws | 14:44:59 |
| hexa | I mean sure, it would kill most of the janky logic | 14:45:14 |
| Mic92 | This was not part of those scripts as well? | 14:45:28 |
| hexa | but the logic wouldn't be so janky if it was just very flat an in a nixpkgs branch | 14:45:47 |

 emily | it would be very sad to give up on Nix/Hydra as the integrated build system for all of NixOS imo | 14:46:22 |
| emily | feel like all this logic could just be … a derivation outputting some symlinks even | 14:46:57 |
| emily | barely even need a manifest | 14:47:01 |
| hexa | per project/jobset buckets with different retention interval is what we thought of for hydra | 14:47:09 |
| hexa | Redacted or Malformed Event | 14:48:00 |
| hexa | I mean, that is still a manifest of sorts :p | 14:48:32 |
| hexa | you are just dumbing it down | 14:48:45 |
| emily | yeah, and cp --dereference is a programmable job execution engine :D | 14:49:04 |
| emily | (but also it's nice if you can do nix build nixpkgs#channel and get the exact files that would be in the channel release dir etc. rather than having to fish them out of JSON) | 14:49:41 |
