What "FUD"?  That I personally am /uncertain/ of the code's ability to
safely disable the journaling?  

Hmm, it's almost like you want me to be onmiscient, and guarantee that
someone else's code will work without fail 100% of the time.

which has *zero* to do with the comment (you removed) stating that the
person (Aragorn?) couldn't tell you anything about that C program.

Good for you.

That's not how journaling works at all.  A filesystem journal is a
(temporary) "scratch list" of actions that are pending completion on the
partition (copies, and locations of the journals depend on filesystem).
Theres no possibility to "work on copies", since the secondary
filesystem has different (or no) journals.

Again, thats not how journaling works.  Say you have a notebook of
everything you need to do today. Now, burn it.

Sure, you can start over with a new notebook, but can you guarantee that
you didn't forget something from the now-destroyed one?
