[ironic]Questions about the use of the build image tool

Hi 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. 发自我的企业微信
