Note that trying to mount a tmpfs with an mpol option will fail if the
running kernel does not support NUMA; and will fail if its nodelist
-specifies a node >= MAX_NUMNODES. If your system relies on that tmpfs
-being mounted, but from time to time runs a kernel built without NUMA
-capability (perhaps a safe recovery kernel), or configured to support
-fewer nodes, then it is advisable to omit the mpol option from automatic
+specifies a node which is not online. If your system relies on that
+tmpfs being mounted, but from time to time runs a kernel built without
+NUMA capability (perhaps a safe recovery kernel), or with fewer nodes
+online, then it is advisable to omit the mpol option from automatic
mount options. It can be added later, when the tmpfs is already mounted
on MountPoint, by 'mount -o remount,mpol=Policy:NodeList MountPoint'.
