:Superb! Exactly what I was waiting for! And this would also solve the
:pruning "problem" we discussed a few days ago -- pruning of files that
:are located in a directory -- and that very efficiently.
I don't think it solves that particular issue completely, but it will
definitely make scanning the directory tree run a lot faster.
:Do you already have an idea how those filesystems-within-a-filesystem

:
: zfs create tank/usr
: zfs create tank/usr/obj

:Would there be a similar tool for HAMMER, or is each directory basically
:a filesystem on it's own? The latter would mean that there is no need
:for such a tool, leading to less administrative overhead.

There would have to be a similar tool. We don't want each directory
to be a filesystem unto itself by default as that would preclude doing
things like, renaming files between directories. Also, each logical
filesystem would have its own object ID space (required for future
replication), so it would become a real mess if we did that by default.
