As with all things, it's probably more complicated than that :-) I personally think that ZFS (from Sun Microsystems) and BTRFS (from Oracle) were originally convergent solutions to the same problem, much like Gnome and KDE both try solve the desktop problem. ZFS started out in the Solaris world, and BTRFS in the Oracle-cloned-Red-Hat world, so there is that difference. Then Oracle bought Sun and now Oracle "owns" both codebases, so who knows what's going in internally at that corporation wrt modern filesystems. ZFS licensing is a problem that should not exist. AFAIK, Sun owned the entire codebase and used their own license. Oracle owns it now, so there doesn't seem to be anything stopping Oracle from releasing the whole thing under multiple licenses, making the problem go away. -- Alan McKinnon alan.mckinnon@gmail.com
