If you
re-do the chkconfig --add on upgrades, won't that overwrite the
runlevel on/off settings that the sysadmin may have customized?
No.
From the man page:
This option adds a new service for management by chkconfig. When a
new service is added, chkconfig ensures that the service has either a
start or a kill entry in every runlevel. If any runlevel is missing
such an entry, chkconfig creates the appropriate entry as specified by
the default values in the init script.
i.e., it only replaces missing links.
