Thanks for the clarification.  Was recalling a past dicussion on how Vinum
determined what belonged to it .

Not using "c" is just plain common sense.

Again? ;)

May try some old pilot errors and see if I can panic it.  Just need to
recall what I was doing, since it happened when (almost) trying to break
things.

Forgot to mention that software should not panic, but if you are doing
something wrong...

Goes back to recent mention of sanity checking.

So then if only the module is loaded and rc does nothing further then doing
a 'vinum read ...' is a Bad Thing.  Use 'start' myself, but just to clarify
for others.

Perhaps I should have been more specific, but from what I understand there
are some issues with the boot process (space limitations?) and possibly
requiring other changes of a more significant nature beyond that, which you
were waiting for to come about first.
