 SomeoneSerge (matrix works sometimes) | FWIW I see no reason not to implement both approaches (host's libs vs. nixpkgs' libs that match the running kernel) in one tool | 23:09:19 |
| SomeoneSerge (matrix works sometimes) | That could be just two flags: --drivers-from={HOST|<nix expr or a flake ref>} and --export=/run/opengl-driver/lib as the alternative to --run <CMD> | 23:12:23 |
| SomeoneSerge (matrix works sometimes) | (and then of course there's this whole libcapsule business that's waiting to be tried) | 23:13:40 |
| SomeoneSerge (matrix works sometimes) | Note there was recently somebody in nix-gl-host issues advertising their Rust rewrite | 23:29:51 |

Has anyone successfully built blender on unstable with CUDA support enabled recently? looks like it's broken since end of October: https://hydra.nix-community.org/build/1720981 | 15:13:24 |

Note there was recently somebody in nix-gl-host issues advertising their Rust rewrite Did you take a look at https://github.com/NVIDIA/nvidia-container-toolkit already? I think they are battling with similar issues, plus sandboxing on top. It seems like they are using ld.so.cache as a loading mechanism instead of the LD_* env var and that might be more robust? | 15:16:02 |

| SomeoneSerge (matrix works sometimes) | I'm not sure if it's worth reusing because nixGL and nix-gl-host are solving a more general problem; the ctk just assumes an FHS environment, we have to patch it and we have to patch its outputs to make them usable on nixos | 15:19:32 |
| SomeoneSerge (matrix works sometimes) | But yes we should keep in mind the general idea of exporting ld.so.cache. We actually used it at least for some time for the singularity containers | 15:21:25 |

Well here's the first offender

| SomeoneSerge (matrix works sometimes) | Ah isn't it nice to have a per-attribute build history | 15:23:36 |
| SomeoneSerge (matrix works sometimes) | So odd that wasn't a thing with hercules | 15:24:15 |

still excited about this one -- plan to add support to optimize zram parameters at some point to see if it's worthwhile to just always disable GC so long as there's RAM (or compressed RAM) available | 06:07:36 |

(yes, it copies the entirety of nixpkgs from one path in the store to another path in the store)
