device or resource busy when trying to rechunk the image in GitLab CI #519
Description
I wanted to try GitLab CI for building my own images and pushing the result in gitlab.com container registry. However, when doing so with BB_BUILD_RECHUNK environment variable defined as "true" it will error out with "unlinkat /var/tmp/buildah1315278245/mounts3091103326/bind4048015439: device or resource busy", without even doing anything after downloading a base image.
