- 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.
+ bool "install dmsetup only"
+ depends on BR2_PACKAGE_LVM2
+ help
+ Install dmsetup only and skip the LVM2 suite.
