Is LVM the best tool to use for snapshots in Fedora 18?
I'm looking for a way to easily roll back a system change during testing and snapshots seem to be a great tool. But is LVM the best way to accomplish that? I may be mistaken, but LVM is no longer a default in Fedora 18, correct? Does that mean it's being deprecated? Btrfs also looks like an option for snapshots, but this document says that Btrfs is still experimental in Fedora 18:
[my karma is insufficient to publish links - see section 9.13.4 of the Fedora 18 Installation Guide for the page I'm talking about]
If you wanted a way to easily roll back your Fedora 18 system after a failed update or test, what tool would you use?
