    How to mount an IMG image in FreeBSD

    1. Determine the file system by using the file-utility.
    file image.img
    Its output should give a clue about the file system. It can be ext2, ext3, ufs, reiserfs etc. Write that one down.

    2. Use the mdconfig-utility to link the IMG image to a virtual device.
    mdconfig -a -t vnode -f /path/to/image.img -u 0
    The image will now be connected to the virtual device /dev/md0

    3. Now mount the virtual device. In this example I use an image with the ext2 file system, so I enter the following command:

    mount -t ext2fs /dev/md0 /mnt
    You can now see the contents of the image in /mnt.

    To unmount the image, enter these two commands:

    umount /mnt
    mdconfig -d -u 0
    You can also mount ISO images using this way, using the file system cd9660 or UDF and mounting it in /cdrom instead of /mnt.
