 K900 | It actually worked surprisingly well | 06:08:17 |
| K900 | I now have a coin battery powered button double sided taped to the outside of my door | 06:08:34 |
 Lyn (they/she) | I'm having this problem with my nixpkgs-unstable override right now, is there any fix? | 17:08:05 |
| K900 | You can't really just stack a package from unstable on top of stable | 17:08:35 |
| K900 | And expect it to work in the general case | 17:08:40 |
| Lyn (they/she) | huh I thought that was the entire point of nix | 17:09:25 |
| K900 | There are intentional impurities | 17:09:48 |
| K900 | There are also unavoidable impurities | 17:10:05 |
| K900 | Like the kernel | 17:10:08 |
| Lyn (they/she) | so this just doesn't work as of now/we have to either use stable or make the full system from nixos unstable?

 @hexa:lossy.network | this was the issue | 17:12:22 |

home-assistant: use unstable jemalloc to match native dependencies
Otherwise home-assistant runs into import errors, e.g. on microvad

| *  philipp is avoiding impurities by having home-assistant in a microvm.nix | 17:15:57 |
| Lyn (they/she) | I somehow managed to have this problem while having this in a microvm already aaaa | 17:19:49 |
| Lyn (they/she) | thanks, I'll try fixing my install to use that module declaration then | 17:20:25 |
| @hexa:lossy.network | are you also using jemalloc? | 17:20:41 |
| @hexa:lossy.network | or is your problem caused by sth else | 17:20:56 |
| @hexa:lossy.network | because you have not yet posted any error | 17:21:09 |
| Lyn (they/she) | seems I just had a skill issue where my override only halfway worked (overrode the homeassistant packages but not the module) which caused a bunch of errors including the jemalloc one. got it to work now. | 17:53:04 |

| @hexa:lossy.network | is that I'm using these days fwiw | 17:54:09 |
| @hexa:lossy.network | hmmm | 17:55:00 |
| @hexa:lossy.network | why don't we have meta.mainLib 😄 | 17:55:06 |
| @hexa:lossy.network | and lib.getLib pkgs.jemalloc resolves to $out/lib/libjemalloc.so | 17:55:26 |
| @hexa:lossy.network | and lib.getLib' to arbitrary librarie names | 17:55:38 |
| @hexa:lossy.network | sorry, that is a bad idea 😄 | 17:55:49 |
