Another question in a similar vein: Which, if any (besides root and nobody, which are a given), of these default accounts are critical to the basic functionality of the box? Is there a list somewhere where I can match these phantom/daemon users to their functionality/dependencies? I'd just as soon blow away things I'll never use, (uucp, xten, etc), but I am loathe to do so without a better understanding of the ramifications thereof....
