Jay pointed out that dir sizes do not necessarily shrink when a number of files are removed, but only expand to their required size upon recreation. So there could be wasted space in some of the original dirs. Another thing, you are comparing a snapshot from some previous time with the state of the /etc directory now. Certainly some things could have changed. Finally see if your system has a dircmp command. Run it as "dircmp /etc /root/etc". It will list any files in one tree but not in the other and then, for each file present in both trees show if they are the same, different, or directories. If you don't have the command, you can do basically the same thing with a series of shell commands. -- Jon H.
