Steps to restore RMS headless (RasPi w/o display) setup on your Linux workstation:
1. create fresh RMS image on a new SD card: unzip -p "RMS_RPi4_image_20210626.zip" | dd of=/dev/mmcblk0 bs=4M status=progress conv=fsync
2. mount the card (e.g. via GNOME Files) and update the hostname in rootfs on the card etc/hostname and etc/hosts (line for 127.0.1.1	<hostname>)

      # Assuming uncompressed image for the unknown extensions
      set -x
      time dd if="$1" of=$2 bs=4M status=progress conv=fsync
