- btrfs_single: One eligible disk. Create BIOS boot (if enabled), ESP 512 MiB, remainder as data. Create a btrfs filesystem labeled ZOSDATA on the data partition.
- bcachefs_single: One eligible disk. Create BIOS boot (if enabled), ESP 512 MiB, remainder as data. Create a bcachefs filesystem labeled ZOSDATA on the data partition.
- dual_independent: One or more eligible disks. On each disk, create BIOS boot (if enabled) + ESP + data. Create an independent btrfs filesystem labeled ZOSDATA on each data partition. No RAID by default.
- bcachefs2_copy: Two or more eligible disks (minimum 2). Create data partitions and then a single multi-device bcachefs labeled ZOSDATA spanning those data partitions. The mkfs step uses `--replicas=2` (data and metadata).

- ssd_hdd_bcachefs: One SSD/NVMe and one HDD. Create BIOS boot (if enabled) + ESP on both as required. Create cache (on SSD) and data/backing (on HDD) partitions named zoscache and zosdata respectively. Create a bcachefs labeled ZOSDATA across SSD(HDD) per policy (SSD cache/promote; HDD backing).
- btrfs_raid1: Optional mode if explicitly requested. Create mirrored btrfs across two disks for the data role with raid1 profile. Not enabled by default.
