Pierrick,

I thought of using rc.local, but idmissed it as running my script prior to 
MySQL starting.  I went ahead and added a line at the end of rc.local and, of 
course, it worked.  And, I call myself a sysadmin.  Yeesh.  Thanks for the 
tip, and for sticking with me.

Given the possible race condition that a dependency might create, is it worth 
it?
