#- name: Back up 4 OS-provided WiFi firmware files (incl symlink contents) to /lib/firmware/cypress/*.orig
- name: Back up 4 OS-provided WiFi firmware files (or replicate symlinks) to /lib/firmware/cypress/*.orig -- NOTE that "doubly timestamped" copies (incl any symlinks' contents!) are ALSO made by iiab-check-firmware -- as firmware install completes
  # copy:
  #   src: /lib/firmware/cypress/{{ item }}
  #   dest: /lib/firmware/cypress/{{ item }}.orig
  #   #local_follow: False    # FAILS TO PRESERVE LINKS (ansible/ansible#74777) e.g. /lib/firmware/cypress/cyfmac43455-sdio.bin -> /etc/alternatives/cyfmac43455-sdio.bin -> ...
  command: cp -P /lib/firmware/cypress/{{ item }} /lib/firmware/cypress/{{ item }}.orig    # "cp -P" == "cp --no-dereference" sufficient to replicate these symlinks and files ("cp -d" & "cp -a" are incrementally stronger, but so far unnec)
  with_items:
    - cyfmac43430-sdio.bin
    - cyfmac43430-sdio.clm_blob
    - cyfmac43455-sdio.bin
    - cyfmac43455-sdio.clm_blob
  #ignore_errors: yes    # 2023-02-25: Let's INTENTIONALLY surface any errors, e.g. if any future RasPiOS or Ubuntu-on-Rpi lack some of the above 4 files/links?

- name: Download higher-capacity firmwares (for RPi internal WiFi, per https://github.com/iiab/iiab/issues/823#issuecomment-662285202 and https://github.com/iiab/iiab/issues/2853)
