 @elvishjerricco:matrix.org | But also ZFS allows you to rollback a mounted dataset no problem | 21:01:00 |
 @hexa:lossy.network | but what does that mean for mountpoints that go missing? | 21:01:16 |
| @elvishjerricco:matrix.org | It makes no sense to me that mountpoints are going missing :P | 21:01:52 |
| @elvishjerricco:matrix.org | hexa: In the emergency shell, does systemctl say the mount units are still active? | 21:04:16 |
| @hexa:lossy.network | yes | 21:05:01 |
| @elvishjerricco:matrix.org | Anything interesting in journalctl -u initrd-nixos-activation.service? | 21:05:55 |

| @hexa:lossy.network | ... does not look like a NixOS installation - not activating | 21:07:17 |
| @elvishjerricco:matrix.org | ahhh | 21:07:28 |
| @hexa:lossy.network | hm, /nix requiredForBoot? 😄 | 21:07:41 |
| @hexa:lossy.network | not sure if I set it or not 🙂 | 21:08:06 |
| @elvishjerricco:matrix.org | No, I see it saying Mounting /sysroot/nix in one of those screenshots | 21:08:27 |
| @elvishjerricco:matrix.org | It's missing /etc/NIXOS | 21:08:32 |
| @hexa:lossy.network | that gets mounted via impermanence 😲 | 21:08:56 |
| @hexa:lossy.network | well bind-mounted | 21:09:20 |
| @hexa:lossy.network | In reply to @hexa:lossy.network
... does not look like a NixOS installation - not activating this begins with /nix/store/....-sytem | 21:10:01 |
| @hexa:lossy.network | so I'm not sure how this would be about /etc/nixos | 21:10:12 |
| @elvishjerricco:matrix.org | hexa: Oh wait, I misremembered what generates that error. It's this: https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/system/boot/systemd/initrd.nix#L487 | 21:11:42 |
| @elvishjerricco:matrix.org | I guess that makes sense if you said /sysroot is empty? | 21:12:22 |
| @hexa:lossy.network | i guess | 21:12:39 |
| @elvishjerricco:matrix.org | I can't imagine why sysroot is empty though | 21:12:50 |
| @elvishjerricco:matrix.org | Oh, I wonder if zfs rollback is erasing the mountpoints | 21:13:36 |
| @elvishjerricco:matrix.org | So maybe I was wrong when I suggested it doesn't matter much when the rollback happens :P | 21:13:53 |
| @elvishjerricco:matrix.org | If the snapshot being rolled back to doesn't have those mountpoints, I'm not sure what happens... | 21:14:16 |
| @hexa:lossy.network | my point exactly 😄 | 21:14:40 |
| @elvishjerricco:matrix.org | So I guess try adding before = ["sysroot.mount"]; | 21:14:45 |
| @hexa:lossy.network | though I would expect them to get created during activation | 21:14:48 |
| @elvishjerricco:matrix.org | That wouldn't help. If a file systems mountpoints simply vanish, then making new directories at the same path wouldn't be reviving the old mount points | 21:15:19 |
| @elvishjerricco:matrix.org | * That wouldn't help. If a file systems mountpoints simply vanish, then making new directories at the same path wouldn't be reviving the old mountpoints | 21:15:21 |
| @elvishjerricco:matrix.org | I'm just... surprised it's possible to make mountpoints vanish | 21:15:31 |
