Roughly how much kernel memory does a filesystem use (even if inactive) --- or did you really mean something like too many pools? The ZFS documentation encourages creating filesystems for everything. I think my (rather beafy) laptop has 20 filesystems now for various tasks --- but I didn't realize there was a non-trivial cost (that is: a cost beyond the mount structure, root vnodes and whatnot)...
