It did work. The usage information is the explanation on how to use
chkconfig. You showed us that it did work successfully to show that usage
(how to use chkconfig) in your earlier email and also included below.

In many cases, that is not related to chkconfig. chkconfig (as I mentioned
earlier) is for managing the symlinks for System-V0-style init.d startup
scripts. As you can see for your output below, it also handles your
xinetd.
You may want to look at dmesg also. Some systems save the dmesg output to
/var/run/dmesg.boot or /var/log/dmesg.out or similar.

Notice the runlevel numbers. You can type runlevel to see the runlevel you
are currently using.
Now look at all of these to see if you really want the script ran (usually
to start a service) for your runlevel.

xfs is an example of something that is generall not needed. It is the x
font server.

portmap is off. That is fine. It is used for rpc services, like NFS.
I wrote an article about this a few years ago ... I see it is at
