Description

Linux Kernel Device Mapper userspace library
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 software raid,
and other drivers that create "virtual" block devices.

This package contains a utility for modifying device mappings.
