 K900 | Well my everything rebuild is done and nothing significant exploded | 04:37:42 |
| K900 | So that's nice | 04:37:45 |
 ghpzin | chromium and electrons do not build:

seems to fix it, probably because rustversion::before from upstream bytemuck is always there on stable. | 20:20:43 |

 vcunat | There's a musl blocker:

Alyssa Ross I guess? | 09:22:00 |
|  teutat3s joined the room. | 09:33:49 |
 Alyssa Ross | Builds locally for me. | 12:33:53 |
| hexa | restarted | 12:34:43 |
| hexa | or rather I clicked and it keeps loading 🤔 | 12:35:56 |
| vcunat | Most likely because eval is in late stage, so a huge postgresql transaction hogs everything involved. | 12:37:12 |
| hexa | that tracks | 12:37:46 |
| K900 | Did we merge a big rebuild into next | 13:28:07 |

| vcunat | On Hydra it looked like wasting around 7k jobs. (but part of that might've been due to other changes) Not that bad, considering that it's *-linux jobs. | 13:37:11 |
| K900 | Ouch | 13:38:14 |
