Ah ok, missed that.
Is the JSON file completely static, listing all modules that were built
regardless of whether they are currently installed, or would it need to
be refreshed when installing/uninstalling RPMs with modules ? I would
think we can do the former and simply handle missing modules on disk
fairly easily
