That's certainly one approach.  The converse -- and this is part of a
different thread, I think -- is to always build and install all
modules, but control what is loaded.  One of the big open issues for
that is how tightly tied to a kernel version a module has to be.  If
they're tightly linked (i.e., because of references to data structures
that may change), I think that having 'build.sh install' handle
modules, too, is by far the right way.  If the coupling is looser --
say, if we had a really stable kernel ABI -- it's more debatable,
though I'd still lean in that direction.  The opposite extreme might be
creating modules.tgz as one of the sets that sysinst optionally
