Hi, thanks for the reply.

Specifying the path doesn't appear to help. I have tried the following:

* Commissioned a new server

* Set disk config in web ui:

    Used disks and partitions

    Name  Model  Serial BootDevice typeUsed for
    nvme0n1PhysicalGPT partitioned with 1 partition
    nvme0n1-part1Partitionext4 formatted filesystem mounted at /

  ** Without these settings I am unable to deploy due to no disk
configuration. **

* Edited /etc/maas/preseeds/curtin_userdata (After early but before late
commands)

    partitioning_commands:
      builtin: [curtin, block-meta, custom]
    storage:
      config:
      - {id: nvme0n1, name: nvme0n1, path: /dev/nvme0n1, ptable: gpt, type: disk, wipe: superblock}
      - {device: nvme0n1, id: nvme0n1p1, name: nvme0n1p1, number: 1, offset: 4194304B, size: 128026935296B, type: partition, uuid: e66f2d9d-963a-4cb9-b2b5-472d491e768b, wipe: superblock}
      - {fstype: ext4, id: nvme0n1p1_format, label: '', type: format, path: /dev/nvme0n1p1, uuid: 6a47f95c-40b6-478a-aefa-ca84a509d877, volume: nvme0n1p1}
      version: 1

** Deployment fails **

If I connect to the failed server I can manually run the commands to try
and see what happened.

* ssh node

* /var/lib/cloud/instance/scripts/part-001

* cd curtin

* cat configs/config-002.cfg

  - {device: nvme0n1-part1_format, id: nvme0n1-part1_mount, path: /, type: mount}

** The above config appears to have ignored my curtin_userdata settings
entirely. **

Any ideas?
