&gt;     &gt; OK, I find the error occurs at the line pivot_root<br>
&gt;     &gt;<br>
&gt;     &gt; I modified this line to to move my container root to &quot;./$odir&quot;<br>
&gt;     &gt;<br>
&gt;     &gt; my command is:<br>

&gt;     &gt; pivot_root &quot;/var/lib/docker/containers/a4aec40cc802b258990c538852387b14ec7f7404ca397c66f2ee6ff9862f4a16/root/&quot; &quot;./$odir&quot;<br>
&gt;     &gt;<br>
&gt;     &gt; the error is: pivot_root: Invalid argument<br>
&gt;     &gt;<br>
&gt;     &gt; any suggestion what&#39;s happening here?<br>
&gt;<br>
&gt;     The pivot_root() only works if the target directory is a mount point.<br>
