DragonFly BSD Releases Version 2.0
An anonymous reader writes "DragonFly BSD 2.0 has been released!
It includes HAMMER, DragonFly's brand-new file system supporting advanced features like history, snapshots and various other cool things. Will it become the new ZFS?
Since it is BSD licensed it could also be integrated into various other operating systems."
No, because a bunch of douchebags keep making them all under licences which do not allow for proper intergration into other operating systems and because HAMMER is designed for distributed filesystem work, a field where there are limited existing systems.
