In the grander scheme of things, I don't think we'll really get
attention to this.  The whole point of Upstart is to ditch sysV init
runlevels entirely.  I don't think any changes that regresses reliance

But thank you for the corrected script..I didn't really like the way the
original one was supposed to work, but I like yours.
