    In article <sm8db2$klb$1@dont-email.me>, headstone255@yahoo.com says...

    I read with interest the uses to which other subscribers
    put their Raspberry Pis, especially those with a whole
    stable of such devices for a gamut of domestic applications.

    But what happens when there is a power cut?

    Do the RPis shut down cleanly? Supposing it is in the
    middle of a data write to the SD card?

    Do they then re-start automatically without human
    intervention?

    IME they usually survive the experience, and reboot cleanly all on their
    own, but occasionally you get unlucky and need to replace the SD card.

    One of my long-standing wishes for Raspbian (er, Raspberry Pi OS) is a supported *reversible* switch in (e.g.) raspi_config to put the SD card
    into a readonly state. There are 3rd party scripts which claim to do
    this, but the ones I've found aren't reversible.

    John, within the Pi-Star software I use there are commands:

    rpi-ro
    rpi-rw

    which do appear to reversible (i.e. you can use them more than once). I'm just a user of these commands.
