We certainly do not want that a permanent variable (one that is listed in the configuration) be erased by accident by an "unset-var" action. Let's make sure these ones are only reset to an empty sample, like at the moment of their initial registration. One trick is that the same function is used to purge the memory at the end and to delete, so we need to add an extra "force" argument to make the choice.
