As Pavel noted, provided you remember only to use safe programs and are absolutely sure that nothing, including the commands in the Makefile you haven't read, will overwrite a file, you are safe.
Come to think of it, chmod -R a-w would be enough to guarantee that for all reasonable programs.
Except Emacs. Some of us turn on backup-by-copying-when-linked even though it breaks the `cp -al' method because turning it off breaks other things. Perhaps I should code an elisp "if editing in /usr/src turn off backup-by-copying-when-linked". :-)
enjoy, -- Jamie
