It so happens that it's ideal for the end-user to do so using tools that
   automate the process.  (Perhaps by installing a package, perhaps by using
   the chkconfig(1) utility [which, sadly, is not yet installed by default]).


chkconfig(8) is wrong and broken.  it overwrites the contents of
the rc.conf.d script if it already exists.  YUCK.  it should use
some ed(1) magic to *replace* such a line, but because the
rc.conf.d is a shell fragment, chkconfig(8) can never be 100%
sure of what it is doing is actually correct.
