I expect that this question will be asked in regard to other features
with lvm as there is a bit of an overlap with the functionality from
other drivers.  As I see it, the advantage of lvm is that it provides
a framework to tie together what are, at the moment, disparate
subsystems.  I have been encouraging Adam to look at how to integrate
pre-existing code into his work wherever possible.
