Here is an example of a failed task because of this issue: https://koji.fedoraproject.org/koji/taskinfo?taskID=17990256
It has to do with the fact that commit and commitmeta` names conflict in ISO filesystems.
commit
Here is an example where we fixed this for Atomic Host in f26: https://pagure.io/fedora-lorax-templates/pull-request/6#request_diff
This seems to have been fixed already (at least for f26 and rawhide), and we're now hitting a different bug.
We have working composes for rawhide, so I'm closing this issue.
