 Tumble | does disko just use nixosModule.config.disko.devices
im thinking i probably dont need to make a lib function and maybe just make a nixos config | 17:59:26 |
 lassulus | yes, depending on what you want to do | 20:02:58 |
| Tumble | i want to just make one disko config where i just specify os drive and optional home and zfs drives and it will make a partition layout the way i want it
and use it across all my systems | 20:46:26 |

| h4rdstyl3z | Hey everyone!
I'm looking into using disko for an upcoming install and I have a question that I couldn't find an answer to in the documentation/examples: is there a specific option that has to be set in order for disko not to format a given partition (for instance, in the case of boot, in which it might not be desirable to format it if you're dual-booting)? The gpt-unformatted example doesn't seem to show any specific option to do that, is it just done through the CLI tool? | 19:32:45 |
| h4rdstyl3z | Ah, apparently this use case is not supported, actually

| h4rdstyl3z | Well, good to know anyhow | 20:44:48 |

| dotlambda | I just asked in #users:nixos.org but I guess since I use disko this might be a better place to ask.
Should I still use options.mountpoint = "legacy" for ZFS in order to avoid issues with systemd competing to mount datasets?

 x10an14 | Hi! I'm also struggling with a Disko/ZFS issue.
I've set options.mountpoint = "legacy".
But when I nix eval the nixosConfiguration, I don't see legacy in the fileSystems attribute?
What am I doing wrong?
$ nix eval .#nixosConfigurations.nas-2024.config.disko.devices.zpool.nvmepool.datasets."root/nix".options
{ mountpoint = "legacy"; }
$ nix eval .#nixosConfigurations.nas-2024.config.disko.devices.zpool.nvmepool.datasets."root/nix".mountpoint
"/nix"
# on nas-2024 during emergency boot mode
$ zfs list nvmepool/root/nix
NAME USED AVAIL REFER MOUNTPOINT
nvmepool/root/nix XXX YYY ZZZ /nix
My config matches AFAICT this post by ElvishJerrico: https://discourse.nixos.org/t/disko-and-zfs-emergency-mode-during-boot/58138/8
