I mean storing most local settings into database, and administrators can modify it online via a dedicated configuration php page. Thus less efforts are needed for administration and updating to new version of mediaWiki. Most page interface messages can be stored in DB, why not to store those essential configuration information? The best case would be to use newversion immediately after unpacking mediawiki-x-x.tar to the original www root. I am tired of editing LocalSettings.php for already. :-) It is like programming, not administration.
