Hi,

Trust me, I've read that section hundreds of times. I'm actually not 
that lazy ;)

I come up with this confusion when I configure a service A 'wants' and 
'after' B. I thought they should be started one by one in a exact order, 
but actually they intersected and run in parallel.

Anyway, thanks for the rely.
