Hi Nicolas,

Thank you for this contribution! I really like some of the ideas you've put
into this set of drivers, especially the part about compressed filesystems!
In the end we're not going to release LVM drivers for 3.4.1. We are going
to wait to the 3.6 to bring them back to the main release.

However I think this will be very useful for many people, so, would you
agree on adding these drivers to the ecosystem?

Also, I would like to borrow the part about the compressed FS and include
it as part of the LVM drivers for the 3.6.

Thanks for your contribution,

Jaime
