'chkconfig' uses comments in the script in /etc/rc.d/init.d/ as hints
to make the symlinks in the runlevel directories (/etc/rc.d/rc1.d,
etc.) for you and some other convenience operations.    The runlevel
directories control what happens at startup and shutdown - based on
your default runlevel set in /etc/inittab.

'service'  executes the script immediately with the argument you
provide.  If you look at the contents of the script you can see what
it does with each argument (stop/start/restart are always handled,
other arguments may be).
