Actually, no, I don't have any such risk -- I didn't trust the database
hooks that much, so I made sure that local administrative and system
user accounts were guaranteed to always be there. It's really not that
difficult to do this safely, securely, and efficiently.

Your decision, obviously, but clearly you face infinitely more risks
(both security and reliability) and suffer greatly from far more
unnecessary overhead than my systems do. Waste-not, want-not. ;-)
