Research direction
Start by reproducing the shutil.copytree failure on Linux with a Lustre source containing files with 440 permissions. Read the copytree handling around os.setxattr and compare the related discussion in issue #68726. Done means the reported copy operation no longer fails when the copied file remains read-only.
