Yah. I think what we are moving towards is more of a one or
two-filesystem model (I think having a separate root is still important),
but to make it totally practical we need to be able to set overall
space limits on a per-PFS basis. (PFS == HAMMER's pseudo filesystems).
This won't happen in the first release but it certainly isn't hard
to accomplish. The advantage of it is that limits applied to PFSs
are soft and could be adjusted up or down at any time. And since
we support 65536 PFSs per HAMMER filesystem the whole mechanism could
be used to soft-partition a huge filesystem for use by different
machines / departments / users / whatever.
No, no quotas for HAMMER yet :-) I just don't think that stuff belongs
in the filesystem. We need a generic quota and MAC layer in the kernel
proper. The MAC layer implemented in FreeBSD is horrible, I think
we could do a lot better particularly with PFS to rough-cut the
