Re: kernel constructor

[Antti Kantee <pooka%iki.fi@localhost>]

There are two separate issues here:

	1: link sets vs. ctors

They are exactly the same thing in slightly different clothing.  Mental 
exercise: define link_set_ctor and run those in kernel bootstrap when 
you'd run __attribute__((constructor)).  As David cautions, I don't 
think ctors should do anything apart from note that X is present in the 
image so that initializing X can be done later.  With link sets you 
don't need the extra step of noting since you can just iterate when you 
want to.


	2: init_main ordering

I think that "code reading" is an absolute requirement there, i.e. we 
should be able to know offline what will happen at runtime.  Maybe that 
problem is better addressed with an offline preprocessor which figures 
out the correct order?
