+ help
+ The default is to support 16 partitions per aoe device. Some
+ systems lack good support for devices with large minor
+ numbers.
+
+ Such systems will be able to use more aoe disks when
+ AOE_PARTITIONS is set to one, but you won't be able to
+ partition the disks, and you must make sure your device
+ nodes are created to work with the value you select.
+
+ If unsure, use 16.
