compile-time options that preclude each other?

If I enable sql  at compile-time then my tests fail unless I also enable 
it at run-time.

Can I enable almost everything at config-time then have a generic .conf 
file that will be used for any application that does not have a specific 
conf file?

What does "rooted in dir" mean?
