Description of problem:
When using oc-mirror to perform disk to mirror by specifying a tar ball on an NFS disk, the unlinkat errors below will cause the command crash on the publish phase. This is the same result when performed by the same user.
unlinkat oc-mirror-workspace/images.1221714546/layout/blobs/sha256: directory not empty
unlinkat oc-mirror-workspace/images.1221714546/layout/blobs/sha256: directory not empty

How reproducible:
Always
Steps to Reproduce:
1. Mirroring from mirror to NFS disk
2. Mirroring from NFS disk to mirror
3.
Actual results:
oc-mirror fails with unlinkat errors
Expected results:
oc-mirror completes successfully
Additional info:
I believe it is caused by .nfsXXXXX files remaining in the directory on the NFS disk. https://nfs.sourceforge.net/#faq_d2
