Many software packages not only support separate, local configuration files, but also provide a special subdirectory to help organize and manage multiple configuration files. In some cases, the files in these directories require a specific extension in order to be considered active or enabled. lbis makes it easy to enable or disable software features. In other cases, all files in the directory are considered as part of the configuration, and a different method is used to enable and disable specific files or features, such as used in the Debian Apache software packages.
In any case, Debian developers usually recommend care in adding your own files, usually by including the word local somewhere in the name, or by placing them in directories that are provided specifically for local files.
