Several additions and corrections have been suggested for the existing "Understanding System Configuration Files" documentation.
- Clarify how config files are used in a clustered environment (do I need to manually propagate the files to all nodes?).
- Clarify whether System Settings stores the configuration values in the database.
- What are the configuration ramifications of purging the osgi/state folder.
- Mention -default config files.
Other various improvements are also necessary.
