I don't think that's needed at all.

Size is a concern, yes. Having too many modules slows down all sorts of
things. I'm not sure, but aren't all modules added to the initrd by default?

Basically, the only thing that I want to see is a specific config for
that kernel, nothing else. Otherwise, it's going to be too much
maintenance work. Indeed, it should *not* be a different source upload,
that's too much work as well. There also may be some optimization that
we could do.

Also, I don't see this happening without a prior agreement from the
kernel team (which means probably that Ben has to agree). On our side,
we could prepare a list of kernel modules that we do *not* want.

Cheers,
