Managing configuration files is a key skill in system administration. Updated configuration files for system suites occasionally ship with new software releases. When available via package upgrade, new configuration files will need to be reconciled with existing ones in a sane manner.

If the system administrator has not modified the existing configuration files, then generally newer files can be 'clobbered' (copied) over older versions. Things become a little more complicated when existing configuration files are modified beyond their original content, and a newer file contains changes that should be merged into the original. That is where configuration management systems become helpful.
