 raitobezarius | i recommend to give up on this or ask yourself why you really want this | 16:22:01 |
| raitobezarius | you can just push encrypted data via a non-filesystem API | 16:22:15 |

you can just push encrypted data via a non-filesystem API yes, this is likely what I will end up doing. | 16:23:20 |

i recommend to give up on this or ask yourself why you really want this I want it because I have been trying to come up with a backup system which is completely transparent. I had my first experience with btrfs send | .... | btrfs receive and it has been glorious. But the problem was that I had to do the luks decryption on the remote side, so it is less useful to me. | 16:26:26 |

But the problem was that I had to do the luks decryption on the remote side, so it is less useful to me because it requires more trust in whoever operates the remote end. So that led me to wonder whether I could do it via luks + network block device (or similar). | 16:29:29 |

you can just push encrypted data via a non-filesystem API I have another (probably very dumb question), but say you used sshfs to mount a remote directory (over the internet, so latency will be a thing), and in that directory there is a 5GB file which you then locally cryptsetup luksFormat ...; cryptsetup open ... ; mount ...; then you write some data to it (say by using dd if=/dev/urandom ... , why does that operation seem to max out at 1MB/s? | 20:48:27 |

| raitobezarius | Buffers? | 21:07:58 |
| raitobezarius | Or TCP Nagle idk | 21:08:36 |
| netpleb | Ok, thanks for your input. I do not have much experience with sshfs either. Maybe sshfs over the internet is just super slow like that. I read somewhere that people get 30-50MB/s when using sshfs on their lan, but maybe it does not work very well on wan | 22:04:57 |

But using the nixos configuration instead of fstab the disko configuration, not the nixos configuration, right? | 11:52:39 |
| @linus:schreibt.jetzt | last I checked disko configuration doesn't provide the full range of functionality you can get via writing fileSystems yourself, especially stuff relevant for impermance-style setups | 11:53:20 |

the disko configuration, not the nixos configuration, right? The nixos configuration that has the disko configuration included | 11:53:21 |
| @linus:schreibt.jetzt | like if I want to have / be a subdirectory of the filesystem, there's no way to represent that in disko | 11:53:55 |
| Mic92 | Linux Hackerman: I think there is an open issue, I haven't responded to, but there is https://github.com/nix-community/disko/blob/master/lib/types/nodev.nix | 11:54:19 |

For zfs we have an impermanence example: https://github.com/nix-community/disko-templates/blob/main/zfs-impermanence/disk-config.nix | 11:57:01 |

| @linus:schreibt.jetzt | I guess that could work with nodev | 11:57:30 |
| Mic92 | I think we also have mountoptions for other filesystems | 12:01:02 |

| Qubasa | Mic92: osdev.org seems to have a similar journey to the nixos.wiki | 01:56:04 |
| Mic92 | Forking wikis is hard. | 04:54:41 |
| Mic92 | If we could have better mechanisms to then sync changes back. | 04:55:11 |
| Qubasa | that sounds like a chatgpt task :) | 10:23:45 |
