+       * NFS export disabled when stack size < 8192 (32-bit Lustre clients),

+       * NFSv4 reexport to 32-bit NFS client nodes requires Lustre client on
+         the re-exporting nodes to be mounted with "32bitapi" mount option
+       * Note for Ubuntu 14.04.5:
+         The 4.4.0 series is the HWE Kernel derived from 16.04 (Xenial).
