Nowadays the Petals µKernel supports:
- to load extension once all its internal component are loaded,
- and to load dedicated implementation of mutable internal component.
In some case, an implementation of a mutable component can require to embed its external resources into dedicated Fractal components (for example, the registry overlay is embedded into a Fractal component to avoid to start another process using the sample configuration). So this Fractal component
must be loaded before the mutable component implementation.
