 @cent:neuland.enterprises | Hi, is it possible to use disko on an already installed nixos system? | 18:21:56 |
| @cent:neuland.enterprises | I would like to configure my btrfs subvolumes in disko | 18:23:12 |
| @cent:neuland.enterprises | (While I originally installed the system I'm talking about with nixos-anywhere and disko I used a dummy flake and later rebuild the system with my usual flake) | 18:24:09 |

| tiddy- | Hey!
Looking to use disko with nix-anywhere for some cluster management (Arguably foaming at the mouth with how simple it looks). My file-system of choice is bcachefs, mainly because the low-cost snapshots and SSD caching.
Looking through the disko examples (and any other sources I've found online) I cant seem to find where to pass CLI formatting options to bcachefs to support options like foreground/background read/writes, encryption, and the like.
Is this a supported configuration by disko? If not (if anyone has time) could someone point me to the working file that actually formats the disk? Might try my hand at implementing something like it. I've found the disko script, but I'd have to brush up on my bash to confirm its the script calling the format command.
Thanks in advance! | 16:08:09 |
 projectinitiative | I was also looking to do the same thing! Unfortunately in the current form, only simple single disk formatting via the mkfs bindings are supported. I created a branch to explore the more advanced use cases, and it does work (ish) for a more advanced setup.
However there are some caveats that will prevent the code from being merged into disko because of the reliance on some external configurations, and a newer kernel implementation. If you are interested, I can write up some basic instructions. If you are feeling like exploring yourself in the meantime, here is how I am using it to provision one of my servers:
https://github.com/ProjectInitiative/dotfiles/blob/main/systems/x86_64-linux/capstan2/default.nix
and my fork of disko:

| food style edible product | I'm having a bear of a time getting KDE logging in after making a live disk with disko-install.
The issue seems to be that /home/foobar is not owned by the user, it is owned by uid 1001. The single user created is uid 1000. (Group id is also wrong, but I assume it's the same issue)
I am also using impermanence.
I have tried:
environment.persistence."/persist".directories."/home/foobar".user = "foobar"users.users.foobar.home = /home/foobarusers.users.foobar.createHome = true- home-manager `home.homeDirectory = "/home/foobar"
Any ideas? | 22:04:00 |

| Marie | Hello, I want to add a new zfs dataset to my existing config, can I just re-rerun the disko format script, or will it destroy old stuff?
I think that should be safe, but I'm not 100% sure from looking at the generated script. | 15:24:53 |

| dantefromhell | I'm looking for a code example to make `extraConfig` pass a `secret.key` file into `vmWithDisko`.
So I can test my encrypted ZFS partitioning scheme | 17:10:40 |
| dantefromhell | @brian:bmcgee.ie have you been able to solve this? | 18:16:56 |

 waltmck | I have a ZFS mirror running as root that was formatted with disko. If I replaced both drives one at a time (i.e. with zpool offline and zpool replace), would the initramfs know where to look to mount the root partition next time I boot? | 15:58:40 |
| waltmck | in my disko config the drives are referred to as /dev/disk/by-id identifies, so I want to make sure that there is no hard-coded fstab entry or anything that uses those | 15:59:56 |
