    Yes, a general shutdown signal scheme makes sense, but still also a
    separate SD unmounting signal to be able to remove just the SD card

      Writing the code last night, it seemed that the shutting down of

      <div class="">Perhaps we need to have new signals “ShuttingDown”
        and “ShutDown”, then make the components responsible for this?
        So, for example, wifi powers off, server v2 disconnects, logging
        stops logging to SD, etc, on “ShuttingDown”. Then SD unmounts on
        “ShutDown”.</div>
