Re: différents répertoires

Freebsd faisait très bien la séparation avant systemd en mettant tout ce qui était conf par défaut dans /etc/defaults ( voir doc:

One of the important aspects of FreeBSD is proper system configuration. This chapter explains much of the FreeBSD configuration process, including some of the parameters which can be set to tune a FreeBSD system.
(...)
FreeBSD base system configuration is located at the /etc directory, and the /usr/local/etc directory contains all the configuration files of the applications installed on the system through the ports collection and packages.
(...)
/etc/defaults Default system configuration files, see rc(8) for more information.
( ...)
The principal location for system configuration information is /etc/rc.conf.
This file contains a wide range of configuration information and it is read at system startup to configure the system. It provides the configuration information for the rc* files.
The entries in /etc/rc.conf override the default settings in /etc/defaults/rc.conf
