-	  LVM2 refers to a new userspace toolset that provide logical
-	  volume management facilities on linux. It is reasonably backwards-
-	  compatible with the original LVM toolset.
+	  This is LVM2, the rewrite of The Linux Logical Volume Manager.
+	  LVM supports enterprise level volume management of disk and disk
+	  subsystems by grouping arbitrary disks into volume groups. The total
+	  capacity of volume groups can be allocated to logical volumes, which
+	  are accessed as regular block devices.
+
+	  The Linux Kernel Device Mapper is the LVM
+	  (Linux Logical Volume Management) Team's implementation of a
+	  minimalistic kernel-space driver that handles volume management,
+	  while keeping knowledge of the underlying device layout in
+	  user-space. This makes it useful for not only LVM, but EVMS,
+	  software raid, and other drivers that create "virtual" block devices.
