 tpw_rules | oh dang. i might try to just revert the qemu upgrade then | 15:53:41 |
| tpw_rules | did you get any further on a diagnosis? | 15:54:27 |

| Artturin | (Just a random rev from my one of my PR branches) | 16:04:21 |
| tpw_rules | i have some spare CPU cycles, i can take some shots in the dark and then bisect. thanks for the reproducer | 16:04:43 |

| Artturin | Sus | 16:06:51 |
| Artturin | Because withPackages discards splicing | 16:07:06 |
 Grimmauld (any/all) | oh that looks like splicing hell | 16:07:11 |
 dramforever | yup that's dead | 16:07:32 |
| Grimmauld (any/all) | https://github.com/NixOS/nixpkgs/issues/211340
nvm no need to tell you, you are well aware | 16:07:35 |
| Artturin | Well easy fix and doesn't need to go to staging | 16:07:34 |
| Artturin | I'll make a pr | 16:07:39 |

# Don't change this to python3 and python3.pkgs.*, breaks cross-compilation
| 16:08:00 |
| dramforever | evidently, not enough | 16:08:06 |
| Grimmauld (any/all) | just python3Packages.distlib ? | 16:08:48 |
| dramforever | pkgsBuildHost.python3Packages... I think? | 16:09:35 |
| tpw_rules | idk really anything about splicing but maybe this is related to some weirdness i've run into in overlays before?? | 16:09:46 |
| Artturin | Probably not | 16:10:05 |
| Artturin | Remember to use callPackage in overlays too! | 16:10:14 |

| dramforever | i s2g | 16:10:39 |
| tpw_rules | i've definitely had issues with the inscrutable difference between python3Packages and python3.pkgs | 16:10:43 |
| dramforever | but how could this break qemu | 16:11:25 |
| dramforever | it's not cross'd qemu right | 16:11:36 |
| Grimmauld (any/all) | just use python3Packages and you'll usually be fine | 16:11:44 |
| Grimmauld (any/all) | also yes good point... Is something using the wrong emulator? | 16:12:01 |
