Just a note that I'd *not* call it "production ready". Btrfs in general is considered "stabilizing, not yet fully stable and mature", as I normally put it. Thus, I'd call that column "stabilized to the level of btrfs in general", or perhaps just "stabilized", with a warning note with the longer form. Because "production ready" can mean many things to many people. The term seems to come from a big enterprise stack, with enterprise generally both somewhat conservative in deployment, and having backups and often hot- spare-redundancy available, because lost time is lost money, and lost data has serious legal and financial implications. But by the same token, /because/ they have the resources for fail-over, etc, large enterprises can and occasionally do deploy still stabilizing technologies, knowing they have fall-backs if needed, that smaller businesses and individuals often don't have. Which is in my mind what's going on here. Some places may be using it in production, but if they're sane, they have backups and even fail-over available. Which is quite a bit different than saying it's "production ready" on an only machine, possibly with backups available but which would take some time to bring systems back up, and if it's a time is money environment, then... Which again is far different than individual users, some of which unfortunately may not even have backups. If "production ready" is taken to be the first group, with fail-overs available, etc, it means something entirely different than it does in the second and third cases, and I'd argue that while btrfs is ready for the first and can in some cases be ready for the second and the third if they have backups, it's definitely *not* "production ready" for the segment of the third that don't even have backups. -- Duncan - List replies preferred.
