I have been a software developer with SUSE for more than 17 years. Currently, I'm the Senior Architect for SUSE Linux Enterprise Server. Previously, I was the primary Project Manager for the product for many years. I have a long history in open source projects.

Nearly everybody has probably run into this situation: after applying updates or other changes to the system, it no longer comes up after a reboot. Especially with a rolling release, this can happen very fast. Most of the time, this means that the system needs to be recovered with the help of a rescue system or even a backup. Wouldn't it be much better if you only needed tell grub, boot the status before the changes were made?

Btrfs has some nice features that can help with this situation: copy-on-write and subvolumes. SUSE has built a solution around these two features that enables an user to boot an older snapshot.

This talk will speak about:
- Btrfs, Copy-on-Write and Subvolumes, how does this work, how does this play together?
- Rollback on openSUSE
- grub2 and rollback
- Caveats and risks
- Cleanup of snapshots
