bootstrapping steppish system

[Rogelio M. Serrano Jr.]

do we make a distinction between boot critical and non boot critical 
local domains?
if I make my Local domain /usr how about "locals" i want to be visible 
at boottime?
If i make my local doman "/" how do i access "locals" in another 
partition?

Or do we want all bootup to be taken care of by /System? Or do we want 
the underlying system to take care of bootup? operating system 
specific bootstrap system?

Right now i have /Library /usr/Library /Applications /usr/Applications 
/Tools /usr/Tools and im beginning to dislike it.
