whatever happened to yum + btrfs snapshotting?

[Neal Becker]

Some time back there was discussion of being able to rollback yum updates via 
btrfs snapshotting.  As I recall, it turned out that the default btrfs install 
was not setup correctly to make this feasible (I had briefly tested it on my 
machine).  I haven't heard anything since - this seems like a great idea.
