 adamcstephens | cool. i need to play with the tool first | 16:56:02 |
 hexa | I can help get it running on the nixos infra then | 16:56:12 |
| adamcstephens | if it has to work with whole images, i'd probably consider making it a local service for users to install | 16:57:06 |
| adamcstephens | sigh | 17:17:18 |

| adamcstephens | may just be easier to generate the simplestreams format ourselves | 17:20:54 |
| hexa | hm, what does it do? copy with permissions? | 17:21:29 |
| hexa | * hm, what does it do? copy with permissions in tact? | 17:21:32 |
| hexa | or does it try to create metadata in the nix store? | 17:22:09 |
| hexa | * or does it try to create stuff in the nix store? | 17:22:19 |

| adamcstephens | the former | 17:25:34 |
| adamcstephens | * closer to the former | 17:25:49 |

| hexa | that code is so very much go | 17:29:34 |
| hexa | to copy a file, open two file descriptors, and then copy between them | 17:29:49 |
| adamcstephens | indeed. the idiom is to make do with the standard library, which is spartan. | 17:30:23 |
| adamcstephens | and 3x the lines for every error check | 17:30:42 |
| adamcstephens | on the plus side, properly passed errors are easy to trace :) | 17:32:15 |
| hexa | so, I'm a bit surprised that you call os.Create(dest) and then don't own the resulting file | 17:32:42 |
| hexa | becausing chowning to foreign uid is only possible as root iirc | 17:33:03 |
| adamcstephens | i wouldn't have called this one properly passed, since no context was added to where it came from | 17:33:04 |
| adamcstephens | this filesystem util is probably mostly used by the server | 17:33:28 |
| adamcstephens | ideally i don't want it to copy the file at all | 17:33:44 |
| adamcstephens | even just trying to generate-metadata wants a write handle on the file | 17:35:04 |
| hexa | sus | 17:35:22 |
| adamcstephens | oh | 17:35:43 |
| adamcstephens | because this is just a wizard to manually create a metadata tarball | 17:36:02 |
| adamcstephens | this whole thing is still sus | 17:37:36 |
| adamcstephens | is there a consumable list of channel bumps ? | 17:43:33 |
