Okay, good because that fits my understanding of how we'd be dividing 
@system from @profile.

@system = the bare set that we need in an stage3 in order to build 
another stage3 via the catalyst process.  so the way this works is that 
you unpack a stage3, chroot into it, and then do a `ROOT=/some/new/root 
emerge @system` to prepare a pristine new root.  that root then seeds 
your stage2 at which point your rebuild your toolchain.  then that seeds 
your new stage3 in which you rebuild @system.

So that defines @system from the point of view of using a current stage3 
to give birth to a next generation stage3.  But that may not be what you 
want to release, eg. do you need any networking stuff in there?  This 
gave birth to the idea of a stage4 which would have the added goodies 
needed for an end user to grow a system from our release tarball.  
vapier is suggesting using @profile for the extra needed beyond @system 
for the release.  So at all points except the very end, you just use 
@system for building because that's all you need, and then finally you 
produce an @system+@profile for release.
