I = have other processes that I would like to have preference over this one = process. Is there a facility that would allow me to assign priorities = based on jail ID or uid? This is on 8-stable (but will upgrade to 9 soon) on ZFS. The straightforward solution is to separate the datasets onto their own = disks, which I'm planning to do, but a software facility would be that = much more flexible.
