 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

| Sofie 🏳️⚧️ (she/her) | Which kernel module? zfs? | 06:31:55 |
| momo | After running disko, you can execute nixos-generate-config --no-filesystems --root /mnt and then compare the generated /mnt/etc/nixos/hardware-configuration.nix with your flake configuration, especially options like boot.initrd.availableKernelModules. | 06:48:38 |
| Sofie 🏳️⚧️ (she/her) | Why do the NVMEs mount then? hmmm | 10:40:03 |
| Sofie 🏳️⚧️ (she/her) | But yeah. I'll try that, thanks! | 10:41:46 |
