      Looking in this link:
      https://docs.openshift.com/container-platform/4.16/edge_computing/image_based_upgrade/preparing_for_image_based_upgrade/cnf-image-based-upgrade-shared-container-image.html#ztp-image-based-upgrade-shared-container-directory_shared-container-directory

      there's the following example:

      [...]
spec:
  clusters:
    - nodes:
        - ignitionConfigOverride: '{"ignition":{"version":"3.2.0"},"storage":{"disks":[{"device":"/dev/disk/by-id/wwn-0x6b07b250ebb9d0002a33509f24af1f62","partitions":[{"label":"var-lib-containers","sizeMiB":0,"startMiB":250000}],"wipeTable":false}],"filesystems":[{"device":"/dev/disk/by-partlabel/var-lib-containers","format":"xfs","mountOptions":["defaults","prjquota"],"path":"/var/lib/containers","wipeFilesystem":true}]},"systemd":{"units":[{"contents":"# Generated by Butane\n[Unit]\nRequires=systemd-fsck@dev-disk-by\\x2dpartlabel-var\\x2dlib\\x2dcontainers.service\nAfter=systemd-fsck@dev-disk-by\\x2dpartlabel-var\\x2dlib\\x2dcontainers.service\n\n[Mount]\nWhere=/var/lib/containers\nWhat=/dev/disk/by-partlabel/var-lib-containers\nType=xfs\nOptions=defaults,prjquota\n\n[Install]\nRequiredBy=local-fs.target","enabled":true,"name":"var-lib-containers.mount"}]}}'
[...]

      Let's have at least one more line in the example, i.e.:

      [...]
spec:
  clusters:
    - nodes:
        - hostName: <name>
          ignitionConfigOverride: '{"ignition":{"version":"3.2.0"},"storage":{"disks":[{"device":"/dev/disk/by-id/wwn-0x6b07b250ebb9d0002a33509f24af1f62","partitions":[{"label":"var-lib-containers","sizeMiB":0,"startMiB":250000}],"wipeTable":false}],"filesystems":[{"device":"/dev/disk/by-partlabel/var-lib-containers","format":"xfs","mountOptions":["defaults","prjquota"],"path":"/var/lib/containers","wipeFilesystem":true}]},"systemd":{"units":[{"contents":"# Generated by Butane\n[Unit]\nRequires=systemd-fsck@dev-disk-by\\x2dpartlabel-var\\x2dlib\\x2dcontainers.service\nAfter=systemd-fsck@dev-disk-by\\x2dpartlabel-var\\x2dlib\\x2dcontainers.service\n\n[Mount]\nWhere=/var/lib/containers\nWhat=/dev/disk/by-partlabel/var-lib-containers\nType=xfs\nOptions=defaults,prjquota\n\n[Install]\nRequiredBy=local-fs.target","enabled":true,"name":"var-lib-containers.mount"}]}}'
[...]

      Note. I personally got confused with the currently documented example, i.e. ended up with something like:

      [...]
spec:
  clusters:
    - nodes:
        - ignitionConfigOverride: '{"ignition":{"version":"3.2.0"},"storage":{"disks":[{"device":"/dev/disk/by-id/wwn-0x6b07b250ebb9d0002a33509f24af1f62","partitions":[{"label":"var-lib-containers","sizeMiB":0,"startMiB":250000}],"wipeTable":false}],"filesystems":[{"device":"/dev/disk/by-partlabel/var-lib-containers","format":"xfs","mountOptions":["defaults","prjquota"],"path":"/var/lib/containers","wipeFilesystem":true}]},"systemd":{"units":[{"contents":"# Generated by Butane\n[Unit]\nRequires=systemd-fsck@dev-disk-by\\x2dpartlabel-var\\x2dlib\\x2dcontainers.service\nAfter=systemd-fsck@dev-disk-by\\x2dpartlabel-var\\x2dlib\\x2dcontainers.service\n\n[Mount]\nWhere=/var/lib/containers\nWhat=/dev/disk/by-partlabel/var-lib-containers\nType=xfs\nOptions=defaults,prjquota\n\n[Install]\nRequiredBy=local-fs.target","enabled":true,"name":"var-lib-containers.mount"}]}}'
        - hostName: <name>
[...]
