Yes.

"chkconfig --add" is only intended to be run once, to create the necessary 
symlinks and get the service recognized by the rest of the operating system 
(especially the "chkconfig" and "service" commands). It will set the 
service off or on at each runlevel depending on what the program's author 
thought was desired. Running "chkconfig --add" more than once accomplishes 
nothing.

"chkconfig service on" will not add or install the service. It will, 
however, set it to "on" for xinetd-related services, and it will set it to 
"on" in runlevels 3,4,5 (and "off" in the rest) if the service is not run 
by xinetd. Why? Because these are the runlevels in which most people want 
to run most services... it is merely providing you with a convenient 
default. In effect, "chkconfig ipop3 on" is equivalent to "chkconfig 
--levels 345 ipop3 on".
