- name: Install packages 'parted' and 'cloud-guest-utils' (for /usr/bin/growpart, though raspi-config uses fdisk)
  package:
    name:
      - parted               # 2022-03-15: RasPiOS and Ubuntu install this regardless -- so rarely nec, but just in case.
      - cloud-guest-utils    # 2022-04-02: For growpart command -- whereas RasPiOS's 'raspi-config --expand-rootfs' instead uses fdisk (requiring a reboot, see do_expand_rootfs() in https://github.com/RPi-Distro/raspi-config/blob/master/raspi-config).  FYI Ubuntu pre-installs cloud-guest-utils, for use with cloud-init.
