elektra-bootstrapping(7) -- default backend

       One important aspect of a configuration library is the out-of-the-box experience. How does
       the system work before anything is configured? The optimal situation is that everything
       works fully, and applications, that just want to load and store configuration, do not see
       any difference in a well-configured, fine-tuned system.

       To support that experience, a so-called default backend is responsible in the case that
       nothing was configured so far. It must have a storage that is able to store full Elektra
       semantics including every type and arbitrary metadata. To avoid reimplementation of
       storage plugins, for default storage plugins a resolver plugin additionally takes care of
       the inevitable portability issues.

       The default backend is guaranteed to stay mounted at system/elektra where the
       configuration for Elektra itself is stored. After mounting all backends, Elektra checks if
       system/elektra still resides at the default backend. If not, it will be mounted there.

       To summarise, this approach delivers a good out-of-the-box experience capable of storing
       configuration. For special use cases, applications and administrators can mount specific
       backends anywhere except at, and below, system/elektra. On kdbOpen(), the system
       bootstraps itself starting with the default backend.

       The default backend consists of a default storage plugin and default resolver plugin. The
       default resolver has no specific requirements, but the default storage plugin must be able
       to handle full Elektra semantics. The backend is not mounted anywhere in particular, so
       any keys can be stored in it. The implementation of the core guarantees that user and
       system keys always stay separated.
