You know that there's a working (though not perfect) bfs_fuse using the current
BFS sources in our repository?

I don't think starting with an outdated file system, updating it with
concepts/features from other outdated file systems is a particularly good
approach. I would focus on what we need, have close look at the (still)
interesting file systems (btrfs, logfs, ZFS, Reiser4), and either fork one of
them or design a new one from the scratch with those in mind. This is a mighty
big task.
Regarding changing the file system interface, that is a necessity and
absolutely desired. E.g. we understand now that queries should not be
implemented in the file system, but rather moved to a userland service.
CU, Ingo
