Define registry.

Sysctl comes close:

- You can make settings changes to the system,
- read values from the system
- is is hierarchical.
- however it is not persistent, but built up from a script or config file.
OTOH, if you would allow only an editor for the config (that sets both
config and sysctl state) it would be pretty equivalent.
