  # ZFS RAID0 (striped, no redundancy) root pool for the bare-metal gui

  # zpool `mode` defaults to "" (plain stripe) when left unset, which is
  # what gives RAID0 semantics here rather than mirror/raidz.
  #
  # Device paths are placeholders until the real hardware profile lands —
  # fill in vars.guiRootDisk1/guiRootDisk2 (stable /dev/disk/by-id/...
  # paths, not /dev/sdX) before running disko against real hardware. Swap
  # is deliberately left out for now — sizing that sensibly needs the
  # box's actual RAM size, which comes with the hardware profile too.
  #
  # Not yet imported anywhere: this awaits the new bare-metal platform
  # module (alongside modules/boot/efi.nix for systemd-boot, matching
  # modules/platforms/proxmox.nix's pattern) once the hardware config is
  # in hand.
