Considering that if you don't have a target for the modules, you don't
have source for it, it is bound to fail, so that is a non issue in
either case.  However, assuming that running kernel == target kernel is
a flawed idea and principle, as said, machines may not even boot without
adding said modules.

Why?   You don't need to own n(n) types of hardware to presume that
drivers built to a kernel may need to be avaiable in order for boot.
Thats a fairly safe presumption for many (pcmcia drivers is a great
example here), and testing to make sure that the idea is safe is merely
about thinking, not even testing to build. 


However, my argument still stands, running kernel should not be the same
as target kernel in any case.  No matter how you solve the situation you
will need a target kernel , even if target == uname -r.

This cuts it down to how to select where the target is, and for this, a
symlink is a very simple way of standardizing it that requires less
cutting into how building works.
