Research direction
Start by reproducing the OCI export on the reported Raspberry Pi, Ubuntu, Docker, and NFS setup, focusing on the mount callback and failed xattr lookup for the /bin path. Trace the export-to-OCI path to determine where the unsupported operation is surfaced. Done means the reported build completes without the xattr failure.
