If you actually have a production system you have to attempt this on Sorry, I should have clarified. It is "in production" but even the production instance is just mostly for education purposes. If I mess it up I will only be mad at myself (and nobody else will be mad at me). | 18:08:46 |
 K900 | What I'm saying is, this is not a thing you should be practicing | 18:09:01 |
| K900 | If anything, the thing you should be practicing is never getting into a situation where you need to do this | 18:09:18 |

What I'm saying is, this is not a thing you should be practicing Yeah, you are probably right. Maybe better for me to figure out how to more automate a reinstall which uses btrfs and disko instead. | 18:10:05 |
| K900 | What you're saying right now is "I'm going to practice building a campfire while being attacked by 30-50 feral hogs" | 18:10:20 |
| K900 | Like | 18:10:24 |
| K900 | Your problem isn't the campfire | 18:10:27 |
| K900 | If you're in that situation | 18:10:32 |
| K900 | You can probably figure out a campfire if you get rid of the feral hogs | 18:10:47 |

What you're saying right now is "I'm going to practice building a campfire while being attacked by 30-50 feral hogs" ha, I almost did refer to it as "trial by fire" in my earlier description -- should have ;) | 18:10:58 |

If you're comfortable with kexec'ing into an image in memory, then it's doable. If you've never done that before, then I'd make sure that you're able to get to the machine in case you mess up do you have a good reference for how I might do the kexec'ing into an image in memory part? I am trying to understand how that is different than the "unmount root without reboot" link above. Will kexecing into an image possibly give me the full effect of as if I had booted into a live thumbdrive? | 18:24:57 |

|  raitobezarius changed their display name from raitobezarius to raitobezarius (DECT: 7248). | 17:10:12 |

|  Sahil joined the room. | 19:54:30 |
| Sahil | I don't know if this is the right place to ask but my nixos home server keeps shutting down and I cannot find a cause via systemctl | 19:54:56 |
| K900 | Is it an x86 server? | 19:55:09 |
| Sahil | yes | 19:55:19 |
| K900 | Do you have anything in /sys/fs/pstore? | 19:56:16 |
| Sahil | empty dir, let me know if theres anything that you might need | 19:58:04 |
| K900 | Check lsmod | grep pstore | 19:58:13 |
| Sahil changed their display name from Sahil Mishra to Sahil. | 19:58:18 |
| K900 | If it's showing anything, you should have pstore set up | 19:58:18 |
| K900 | So any logs possible will be, well, logged | 19:58:25 |
| K900 | Even after a kernel panic or something | 19:58:29 |
| K900 | So if you still have nothing, it's probably hardware | 19:58:36 |
| Sahil | efi_pstore 16384 0 | 19:58:42 |
| K900 | Then yeah, it's likely hardware | 19:58:54 |
