RFC: Btrfs snapshots feature for F13

[Chris Ball]

Hi,

I've written up a draft of an F13 filesystem rollback feature using
Btrfs snapshots that are automatically created by yum:

   https://fedoraproject.org/wiki/Features/SystemRollbackWithBtrfs

It'd be great to get feedback on whether this is the right idea, and
how exactly the UI interaction should work, before submitting this
formally.

Thanks!

- Chris.
