What steps should we be taking now?

For starters we need to get rawhide's yum-utils updated to include the
latest fs-snapshot plugin updates that are now upstream.

Who should update the SystemRollbackWithBtrfs page?  Or should we create
a new SystemRollbackWithLvm page that is linked to from
SystemRollbackWithBtrfs?

I'm open to helping answer any questions David might have, and making
any lvm changes needed to assist his effort, once he has time to look at
gnome-disk-utility's snapshot integration (via lvm and btrfs).

It would be nice if gnome-disk-utility knew to treat LVM snapshot LVs
that have a "yum_<date>" tag as being part of a "system rollback point"
or some such.  But I'm not sure of the best way for David to
programatically (or via lvm utility) access a snapshot LV's lvm tag(s).
A stop-gap would be to just rely on the suffix of the LV name to end
with: "_yum_<date>" (but that is fairly crude!)
