I started toward figuring that out for Plan 9 by putting together the kernel history at http://swtch.com/plan9history. Step 2 is understanding every change and categorizing them, including whether or not they are bug fixes. Then one can derive many interesting statistics about the bugs. I got about a quarter of the way through categorizing http://swtch.com/cgi-bin/plan9history.cgi?p=3D^(pc|port)/.*\.[ch]&v=3Dfilel= ist I'm hoping to find a student at MIT to finish the job. Russ
