+Concatinating and removing interface files
+
+Debian based distributions have `/etc/network/interfaces.d/` directory, where
+you can store configuration of network interfaces in separate files. You can
+concatinate the files to the defined destination when needed, this operation
+removes the file from the `/etc/network/interfaces.d/`. If you just need to
+remove iface files, you can use the `remove_iface_files` key.
