or "How do I know my copy of FreeBSD is the same as yours?" I have recently been meditating on the issue of validating X.509 root certificates. An obvious extension to that is validating FreeBSD itself. Under "The Cutting Edge", the handbook lists 3 methods of synchronising your personal copy of FreeBSD with the Project's copy: Anonymous CVS, CTM and CVSup. There are
