Its official, we have snapshot support in the forthcoming ASL 2.6.22.9 kernel. I might also take a moment to mention we also have a 2.6.22.9 kernel. Back to snapshots though, we're using what is known as a "Time Shifting File System" (TSFS), it allows you to create snapshots of the disk as a whole, like you can with LVM. Snapshots can also be created as a user. The idea at this point are to build this into both the ASL interface for rapid backup/recovery, as well as at the domain level to enable the users to backup/restore their own data. Snapshots themselves are filesystem level diffs, so in terms of space they use a fraction of the total disk size.
More than anything else, this is designed to take the fear out of upgrading. If it fails, you just revert the system to the way it was before, and all is well again. Ubiquitous screenshot of QT-based file browser that can read a TSFS.
