How to mount an IMG image in FreeBSD 1. Determine the file system by using the file-utility. Code: 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. Code: 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: Code: 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: Code: 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.
