    Yes this is what I want.

    I was hoping I can add some rule based on regex in
    /etc/apt/preferences.d that will accomplish this. Well, if there
    isn't one then there is nothing much I can do. 
    
    Since the system is accessible by ssh even if screen goes blank by a
    imperfect install of just linux-image, I can always ssh and then 
    install headers and reinstall image to get nvidia-driver rebuilt and
    reboot. So, it is not that I am completely broken without this rule,
    but I wish it is something that can force/automate. 
    
    Thanks for taking the time to respond with detail.
    
    Before I go, I have one question. When I try to install linux-image,
    apt tries to trigger a nvidia-driver build, but fails because
    headers are not present. However, it still completes the image
    install and changes grub menu etc. I prefer it stopped and
    complained. Is there a way to tell it to error out on this step, so
    that I will be prompted to look at this more closely? Typically,
    this message flies by on the screen and I was lucky that I saw it
    the last time.
