As Kushal pointed out, packages that expect to interact with other
random packages (e.g. cron with /etc/cron.d) often provide a
subdirectory that they read. Some others provide a program interface to
modify configuration (e.g. update-rc.d).

Other than that, it's usually a bad idea to attempt to modify other
packages' configuration files. If it's a conffile, it's explicitly
forbidden by policy. See policy 10.7 and especially 10.7.4.
