That's a good point.  We need to retain in-the-background runability,
so perhaps moving the old to a backup location and modifying the new
one would be the best solution.

Thank you for the reminder.  You are 100% right, and in fact, the hash
system right now does not even work for Orion.  I will think on this,
because ... yeah.  It needs to be looked at and rethought, I think.
Thank you.
