Don't Overwrite Config files

Thank you for your reply. I think I may not have been clear in what I'm
doing, so let me try to clarify in case it changes the answer. The config
files I'm dealing with arenot a configuration file for a port, it's
configuration files *provided by* a port, for use by the system.
Specifically, SSH and Kerberos config files for use in an institutional
deployment. It does not scale to make every user in the organization have
to manually move the config files to the correct place. What would you
suggest here? Any assistance would be most appreciated.
