Yeah, but isn't that the kind of thing that could be 'slow' the first 
time, but lickety-split after the inital run?

For instance, as part of the system install (and after appropriate 
daemon/software installations) a table of all possible dependencies is 
constructed (perhaps as some kind of tree).

This table is then optimized/compiled (and subsequently 
re-optimized/recompiled) into a file of some kind of intermediate 
format. This file is then used by the boot process to drive system 
configuration/behaviour and is represented by the changes that were made.
