What he is saying is, if I want to control the size of a directory, but
there will be file creations in that directory from more than one user, I
need to do something besides quotas, since quotas only count how much that
user has created, NOT how much is in the directory total.

So my question was, is there a way to control how big a directory can
grow, regardless of who is putting what files in that directory.

So far, his answer was that I could just make each directory its own
filesystem, which would definitiely work, but I wondering if perhaps there
is a more elegant way to do this ?

Again, I am just trying to take an arbitrary directory, say:

/export/data7/homes/jerry

and place a configurable limit on how big that directory can get, without
mounting it as its own filesystem...

thanks.
