| bandithedoge | thanks | 17:34:54 |
 Jassuko | Oh, I forgot to mention. I dug up some older MiniPC that had Nixos 24.05 or .11 stable channel in it. I tried to get it to current unstable which failed with a weird substitution failure. I noticed it had non-lix nix in use so decided to try run the nixos-rebuild within a nix-shell with lix. To my surprise it actually worked. Lix FTW yet again. :D | 17:39:58 |
| Jassuko | Kinda "lol, no way this is going to work" yolo moment, but here we are. :D | 17:41:08 |
|  @myujiku:matrix.org left the room. | 18:47:51 |
 leona | yeah interestingly 24.05->25.05 is reliably not possible with Nix | 18:48:47 |
 K900 | Huh, why? | 18:53:38 |
 raitobezarius | leona: this got me semi curious, Jassuko does anyone of you has the exact error you receive? | 18:53:51 |
| raitobezarius | i want to know if my bet of what it is — is correct or not | 18:54:03 |
| leona | let me check, I can probably get it | 18:54:10 |
| raitobezarius | thx | 18:54:16 |
| leona | path '/nix/store/cy03cdv5c7a7chnm0zq263620invrmd8-linux-6.12.35-modules-shrunk/lib' is not in the Nix store
| 18:57:19 |
| raitobezarius | alright, thanks | 18:58:18 |
| leona | we got that reliably at work on every VM (Nix 2.18.8 on 24.05) | 18:58:34 |
| leona | with a step on 24.11 it works just fine | 18:58:48 |
| raitobezarius | this is an exportReferencesGraph that happened between 2.18.5 and got fixed by 2.18.9 | 18:59:27 |

| raitobezarius | bug exacerbated by nixpkgs in https://github.com/NixOS/nixpkgs/pull/372931 | 18:59:59 |
| K900 | Oh god | 19:00:15 |
| K900 | It's that fucking cppnix bug | 19:00:17 |

Fix exportReferencesGraph when given store subpath
With Nix 2.3, it was possible to pass a subpath of a store path to
exportReferencesGraph:
with import <nixpkgs> {};
let
hello = writeShellScriptBin "hello" ''
echo ${toString builtins.currentTime}
'';
in
writeClosure [ "${hello}/bin/hello" ]
This regressed with Nix 2.4, with a very confusing error message, that
presumably indicates it was unintentional:
error: path '/nix/store/3gl7kgjr4pwf03f0x70dgx9ln3bhl7zc-hello/bin/hello' is not in the Nix store
(cherry picked from commit 0774e8ba33c060f56bad3ff696796028249e915a)
