Rollback on BTRFS (Thorsten Kukuk, SUSE)

BTRFS is a Copy-on-Write filesystem, which allows you to create snapshots very easy. With snapper, there is a tool which can create snapshots and allows you to restore single files. But what happens if your kernel update is broken, your initrd got corrupted or you cannot boot the system anymore for other reasons? Wouldn't it be nice to be able to boot an older, working snapshot?

New snapper versions have a new functionality for this: rollback.
With this, you can do a full system rollback to an older state.

This session will explain the benefits of it and how to use it. Additional, it will show some common pitfalls and how to avoid them, like which requirements are there for the partition layout, when a rollback can work, when not, and what happens with my data.
