Btrfs and raw zvol-like partition

["Sébastien Wacquiez" <sw@enix.org>]

Hi,

A nice feature is ZFS is the "ZVOL" layer, that permit you to export=20
(directly) a raw device from your zfs pool of disc, with the benefit of=
=20
powerful (growing!) snapshot and easy raid management from zfs. It's=20
particulary usefull when you use it with virtual server, allowing you t=
o=20
centralize all your backup problematic, etc

Does btrfs plan to support this kind of feature ? (please, don't tell m=
e=20
that lvm do, lvm just sucks when you make a snapshot of your disk, and=20
lack of the "growing", commit, rollback, diffsend feature).

Thanks !

PS : see http://opensolaris.org/os/community/zfs/source/zfstour.png if=20
you don't know what zvol do.
