Most configuration files reside in the / ete directory hierarchy. In general, most packages place their configuration files in a subdirectory named after the software. In cases where the upstream developers do not do this, the Debian package usually modifies the behavior. A good example is the BIND DNS server software. Traditionally, the base configuration is placed in /ete/named. eonf, with any other configuration files placed in the /var/lib/named directory. The Debian BIND package places all configuration files in /ete/bind9 and its subdirectory.
In addition, there is a fete/default directory, in which commonly modified options are placed in a file matching the package name. Again, using BIND, the file is /ete/ default/bind9, and contains two simple options: whether the resolveonf dynamic resolver is being used, and what options the server should be run with. We'll cover this directory first.
