They doesn't need to. The configuration is the realm of the package
based on system defaults/parameters. This is done in pre/post install
scripts. Of course, there are helpful mechanisms such as alternatives,
standard configurators, &c. Finally, there are policies enforced by
various tools. Speaking as someone that have done, professionally Debian
and RedHat packages.
