• Possible to mount the Pi OS .img file using loopback?

    From Adam Funk@3:770/3 to All on Wed Oct 18 13:29:50 2023
    Hi

    I've downloaded 2023-10-10-raspios-bookworm-armhf.img.xz, used unxz to
    extract the .img file, and I'm trying to mount it so I can have a look
    at some of the files in it. I was trying to avoid having to write the
    image to an SD card.

    $ file 2023-10-10-raspios-bookworm-armhf.img 2023-10-10-raspios-bookworm-armhf.img: DOS/MBR boot sector; partition 1 : ID=0xc, start-CHS (0x40,0,1), end-CHS (0x3ff,3,32), startsector 8192, 1048576 sectors; partition 2 : ID=0x83, start-CHS (0x3ff,3,32), end-CHS (0x3ff,3,32), startsector 1056768,
    9297920 sectors

    $ sudo losetup -f --show 2023-10-10-raspios-bookworm-armhf.img
    /dev/loop0

    $ sudo mount -t auto /dev/loop0 /mnt/image/
    mount: /mnt/image: wrong fs type, bad option, bad superblock on /dev/loop0, missing codepage or helper program, or other error.

    I thought these image files were supposed to contain mountable
    filesystems, and I'm (almost) sure I've done this before with raspbian
    and Ubuntu images --- am I doing something wrong above?

    The image file has multiple partitions, so you need to mount the partitions within the image, not the raw image itself. You either need:

    $ sudo losetup -f -P --show 2023-10-10-raspios-bookworm-armhf.img

    and you'll get devices per partition: /dev/loop0p1, loop0p2, etc

    or, on an existing loopback device,

    $ sudo partprobe /dev/loop0

    and it'll create the partition devices.
    Then you can mount them:

    $ sudo mkdir -p /mnt/boot /mnt/root
    $ sudo mount /dev/loop0p1 /mnt/boot
    $ sudo mount /dev/loop0p2 /mnt/root

    Brilliant, thanks very much!
