-NFS enforces file creation on different UIDs on the server side and does not understand User Namespace.
+NFS enforces file creation on different UIDs on the server side and does not understand user namespace, which rootless Podman requires.  When a container root process like YUM attempts to create a file owned by a different UID, NFS Server denies the creation.  NFS is also a problem for the file locks when the storage is on it.  Other distributed file systems (for example: Lustre, Spectrum Scale, the General Parallel File System (GPFS)) are also not supported when running in rootless mode as these file systems do not understand user namespace.
