NixOS + ZFS: zpool import script fails, "/dev/disk/by-id" is empty

Help
1

The systemd script generated by ‘nixos/modules/tasks/filesystems/zfs.nix’ fails to import the ZFS pool because there are no devices in “/dev/disk/by-id”.

I solved it by setting boot.zfs.devNodes = “/dev”.

But why is “/dev/disk/by-id” empty?

Could you please share your config?
