ok this seems to do the trick....
it could be nice to have some documentation that explain what are the 
DefaultDependencies.... I hate that someone choose to do something for 
me without beeing aware of it.... at least when enabling a service 
display it's Dependencies...
it's just my point of view, but for me, what isn't in the service file 
shouldn't be executed... when I ask a coffee, I don't want that charge 
me a sweet in addition....
thanks for the reply
