Event driven *enough*?  What do you mean?  How can it be more or less 
event driven ( in other words, either it is or is not, there isn't 
really an in between )?  When the drive add event comes in, udev runs 
dmraid to activate the array.  As long as that happens before 
wait-for-root gives up, all is well.

If you're getting timeouts, then either the timeout is too short, or you 
have some VERY slow initializing hardware.  How would upstart help this?
