You may be right. Perhaps you can help me with this statement found in https://www.netbsd.org/docs/current/#tagging --snip-- Tagging a successful build If the build completes successfully, and produces a working set of binaries, it can be useful to tag the working sources. This allows rewinding to a working build tree with a single CVS command in the event that the current tree becomes unbuildable for any reason. This can be performed by issuing the following command: $ cvs tag successful-build-build date --snip-- My execution of that command (issued in /usr/src) yields: $ cvs tag successful-build-build date cvs tag: nothing known about date cvs [tag aborted]: correct the above errors first! -- "...that there is no getting away from the central position of the individual I believe anyone can see for himself merely by observing that the individual does not regard the following to be a senseless question: "Under what conditions would you draw the conclusion that everyone in the world except yourself had gone crazy?"
