Any update? Shared snapshots is still top priority. We ended up scrapping the first design as it became apparent that people really wanted arbitrary depth of recursive snapshots (snapshots of snapshots of snapshots ...) and we hadn't allowed for that. Currently myself and Heinz are working full time on the kernel side. This includes a new metadata transaction library that will be used by shared snaps, thin provisioning and hierarchical storage. Expect an experimental version of thin-provisioning sometime in January. The others should follow swiftly since they all have a lot of common code. I'm not sure how long it will take to get from 'experimental' to 'production ready', obviously the more people that help us test, the quicker this process will be. - Joe
