Unix provides uid and gid to act upon processes. Normally, you have to either be the owner (or effective owner) or root to kill a process. Mach provides this via capabilities so that anyone with the proper capability could do it. Can anyone give me references or anecdotal evidence that Mach uses capabilities to give a different look to permissions than Unix provides? That is, do Mach users take advantage of the greater generality provided by capabilities? thanks rich
