Cloud Provider: Azure
dpkg-query -W -f='${Version}' cloud-init output: 0.7.9-90-g61eb03fe-0ubuntu1~16.04.1

When the following is specified in cloud init it seems to be re-executing fs and disk setup (even though run command does not seem to re run)
disk_setup:
  /dev/sdc:
      table_type: gpt
      layout: true
      overwrite: false

fs_setup:
- label: etcd_disk
  filesystem: ext4
  device: /dev/sdc1
  extra_opts:
    - "-F"
    - "-E"
    - "lazy_itable_init=1,lazy_journal_init=1"

mounts:
- - /dev/sdc1
  - /var/lib/etcddisk
