Help text

Device-mapper is a low level volume manager. It works by allowing people to specify mappings for ranges of logical sectors. Various mapping types are available, in addition people may write their own modules containing custom mappings if they wish.

Higher level volume managers such as LVM2 use this driver.

To compile this as a module, choose M here: the module will be called dm-mod.

If unsure, say N.
