 Wanja Hentze | If you're going to pretend things never go wrong, might as well not have rollback either | 22:35:44 |

Magic rollback should be part of NixOS to a certain extent the rollback part yes (and it is), but the "can I still use my deployment tool on this machine" part depends on the deployment tool | 22:38:20 |

If you're going to pretend things never go wrong, might as well not have rollback either that's the goal | 22:38:43 |
| raitobezarius | trying to rollback is already defeat | 22:38:51 |
| Wanja Hentze | we have that today | 22:38:57 |

| void | * colmena will ssh touch /tmp/done_switching; for instance in the test section. | 23:18:26 |
| void | this will save me from pretty much all the mistakes I make (too hot here 33 deg cel during the day, can't concentrate sometimes) | 23:19:25 |
| Wanja Hentze | yep, it's quite low-tech | 23:53:04 |
| Wanja Hentze | can be built out of an activation script and a "post-apply" script on colmena's end | 23:53:30 |

issue is i can reproduce it consistently, and it only happens when using it via Colmena :/ I've been seeing the same thing with Colmena recently, trying to re-use the master socket just hangs. The only thing that fixes it is if the master socket gets closed, either explicity, though a timeout, or if the remote system reboots. | 00:19:49 |
| Jeff | Only happens with Colmena, never have a problem with the ssh client. | 00:22:21 |
| Jeff | I wonder if the recent update of openssh to 9.3p2 or 9.4p1 is part of the problem. | 01:35:20 |
 Zhaofeng Li | Quickly looked, and it appears that the underlying problem may be https://github.com/NixOS/nix/issues/8329 | 05:14:50 |
| Zhaofeng Li | I'll try to reproduce with nix-copy-closure on an older Nix version tomorrow. Should have looked earlier when I first encountered the problem myself 😐 | 05:16:33 |

Quickly looked, and it appears that the underlying problem may be https://github.com/NixOS/nix/issues/8329 Looks like this is fixed in Nix 2.16 but that will take some time to roll out. A workaround would be a way to disable ControlMaster for Colmena/Nix connections but I don't know how you'd accomplish that. | 14:47:49 |
