95Note that trying to mount a tmpfs with an mpol option will fail if the
96running kernel does not support NUMA; and will fail if its nodelist
97specifies a node >= MAX_NUMNODES. If your system relies on that tmpfs
98being mounted, but from time to time runs a kernel built without NUMA
99capability (perhaps a safe recovery kernel), or configured to support
100fewer nodes, then it is advisable to omit the mpol option from automatic
101mount options. It can be added later, when the tmpfs is already mounted
102on MountPoint, by 'mount -o remount,mpol=Policy:NodeList MountPoint'.
