Yes, device-mapper is the kernel component that LVM2 uses to create
logical volumes so it can also support pretty much arbitrary numbers of
logical volumes (although LVs aren't normally partitioned unless you use
a tool like kpartx).
Device-mapper's also used by applications like multipath-tools, dmraid
and kpartx itself.

Bryn.
