Once thing to keep in mind when turning off services is to use update-rc.d 
correctly.  It's not a good idea to turn off services using 
"update-rc.d -f remove" because that completely removes the links for a 
package.  If the links are completely removed, then when the package is 
upgraded the links will be restored and the service will start up again at 
the next reboot.  The correct way to turn off a service is to remove all of 
the links except for one Kill link.  That way the service won't start and 
won't be restarted when the service is upgraded.
