Yeah. The whole Linux security model seems like it was designed centuries ago. Your permissions are supposed to derive from the authority granted to you at the time of your invocation, and from those with the existing authority to grant/delegate them... not from your lineage, name, possessions, or status at birth. I find it kind of funny that generations of *nix engineers appear to have perpetually struggled with this concept. For all the hate it gets, Windows got this part fundamentally right.
