If you're using BEES, you don't have a choice: it runs on the whole filesystem. If you're using duperemove, there is a read-only mode where it tells you what it would do but does not do it. Neither one will cause problems because of ownership or permissions differences -- that metadata will remain intact for each referenced file. You are unlikely to be saving much space overall, unless your family is in the habit of copying media files back and forth or something similar. -dsr-
