Why on earth would you have log files in the Root? You are putting your whole USS environment at risk. One out of control user could kill the system....

To me, the problems with HFS and ZFS files seems to be a design flaw. When I was at P&H Mining, we had the same problem. The root file kept growing - mostly I think because of logging activity. The files were kept for only a week and then automatically deleted, but the HFS file just kept getting more extents. It never made sense to me, when the total amount of data wasn't groing..
