  • Re: readonly installer, (SOLVED)

    From Stefan Monnier@21:1/5 to All on Sat Apr 6 09:50:33 2024
    I have a 128 MB USB flash drive from back in the day that includes a write protect switch. There are few products today that offer that feature.

    Side note: AFAIK this "write protect switch" doesn't prevent writing.
    It just tells your card reader that you'd like to avoid writing to it.
    Whether it ends up doing what you want depends on the hardware exposing
    that info to the driver and the driver paying attention to it.

    A friend of mine just let me use an external CD-Drive with the netboot image.

    I thought about suggesting that in my last post, but did not want to complicate things. A key advantage of using a CD-R disc is that you
    can verify the disc contents and/or checksum against the ISO and/or
    checksum now and in the future. This is not true for a USB flash
    drive, because the Debian installer modifies the contents of the USB
    flash drive when it runs.

    If this troubles you, you can also use an SD card with a write-lock,
    or a µSD card with a lock on the SD adaptor.

    Check that the write-lock works with the logs when you plug it in,
    or run fdisk/gdisk and immediately quit.

    Cheers,
    David.

    No, it is a USB flash drive with a write protect switch. Here is a
    modern example:
