title: Can't mount image file via loop option to on of my home subdirectories
body: <p>I'm trying to mount an image file via loop option which contains ext4 filesystem but it fails with an error message &quot;mount: ./mountpoint/: failed to setup loop device for /home/mikayel/asd.img.&quot;:</p>
  <pre><code>$ truncate -s 100M asd.img
  $ mkfs.ext4 asd.img
  $ mount -o loop asd.img mountpoint/
  mount: ./mountpoint/: failed to setup loop device for /home/mikayel/asd.img.
  </code></pre>
  <p>I'm trying to make a build script which will make a <code>rootfs</code> image. The build script neither can be run using <code>sudo</code> nor it can ask a sudoer password (e.g. if I change the <code>mount</code> command to <code>sudo mount</code>).</p>
  <p>Is there any way I could do it without root privileges ?</p>
