"A default installation of Red Hat includes a lot of
software; most users will never need much of it. For example, if
you are a workstation user, and all you are using Linux for is
browsing the Web, do you need a DNS server running? Or the Network
File System (NFS) service? Chances are you don't."
"Now, there are a couple of ways you can remove a service. The
first is to remove the software package that runs the service. The
second is to use the chkconfig command to remove the service from
the run level. To remove the software package, you would use the
command rpm. For more information on rpm, please see the man
"Removing the service from the run level has some benefits over
removing the whole software package. If you remove the service from
the run level, you won't have to remove the software and you can
always use it later if the need arises. Also, you may only want to
remove the service temporarily -- to debug a problem, for example.
The chkconfig command can also be used to specify which run level
you would like to have a particular service run in."
