The SoL philosophy has been that the system user (or administrator) has complete control over the system and knows exactly what to do. The SoL developers think that they should not provide a set of predefined configurations for such complex systems, and therefore provide the services "as is", like they are meant to be when provided by the creator. Hence, SoL does not provide bloated global configuration monsters that explode in flames when you do minor changes. Only very simple basic "system"configuration tasks are handled by SoL, like the starting of services and the configuration of the keyboard and network.

Since, SoL was created by the developers and administrators of OSNET.at for developers and administrators, it is a perfect platform for servers and for developing server applications. SoL features:
