preOpenStack

[dunbarx at aol.com]

It actually is a bit counterintuitive that a card can receive a preOpenStack message. After all, the whole (ostensible) idea is that "preOpenstack" is sent before the stack opens, so how could there even be a card to send that message to.


It is all mainly a matter of drawing, though, not what is actually is existence. The wording is a bit misleading is all...

As you yourself quoted, "the message is sent to the destination *card*".
The card has the first crack at handling the message.

If the handler is in the stack script then it's accessible at the root of
the message path from any stack in the ecosystem. Placing it in the card
script localizes its effect.
