Other shared objects besides system:rtems.so may be installed. In general, a shared objects object that the dynamic linker loads in order to satisfy a dependency it will also install if the shared object requests it. In such a case that single loaded copy is used whenever named as a dependency not only in that run of the linker but in all subsequent runs. In any given run of the linker it will load any object only once, but those objects that are not installed will be re-loaded if need be in subsequent runs, ignoring any copies loaded in previous runs.
