Good project here for a brave coder:

Allow start-up scripts to only specify their dependencies (they can
declare packages that must be init'ed before them). At start-up time,
work up the graph from the bottom, guaranteeing only to start things
after their dependencies are already running.

This has two major advantages:

a) You can always add another package 'between' two existing ones.
b) It exploits as much parallelism as possible.

It's not even that hard to code ;-)


PS I think MacOS X does it this way, as it happens
