    # File: /etc/apt/apt.conf.d/docker-autoremove-suggests
    # Since Docker users are looking for the smallest possible final images, the
    # following emerges as a very common pattern:

    # RUN apt-get update \
    # && apt-get install -y <packages> \
    # && <do some compilation work> \
    # && apt-get purge -y --auto-remove <packages>

    # By default, APT will actually _keep_ packages installed via Recommends or
    # Depends if another package Suggests them, even and including if the package
    # that originally caused them to be installed is removed. Setting this to
    # "false" ensures that APT is appropriately aggressive about removing the
    # packages it added.
