              <div>We are using diskimage-builder to make a custom
                image, There is a problem in extract_image, The question
                is chroot: failed to run command 'bin/tar': No such file
                or directory, I found the /bin/tar file in the working
                directory /tmp/ tmp.00yldwe1xt. But errors are still
                being reported. It's not clear if this is a custom image
                problem, There are also requirements for custom images.</div>
