Here is an interesting paper, that explores the dependencies 
between modules in some open source kernels (linux vs BSD).

The paper found the linux kernel (compared to the BSD kernels) 
had far too much dependency between modules, because linux uses 
far too many global variables, and so too many modules are 
tightly coupled by mean of them sharing those global variables.

They argued that such common coupling (module dependencies) have 
a deleterious effect on maintainability, and that such common 
coupling increases exponentially with each subsequent release, 
further reducing maintainability.

The key take away point of course, is that software development 
really needs to be on guard against the problems associated with 
modular dependencies.

It's one of the reasons functional programming is becoming 
increasingly important (and useful).

There is no reason why the principle should not also apply to the 
distribution of software.
