That's just what I do and what I know about. I'm reading about dracut
here, but I don't know how easy that is. Sure, I also wouldn't like an
additional layer, but what if there are no good alternatives?

Yes, I remember the discussion. But I think you used genkernel as it was
designed, to generate a new kernel .config from scratch. This is not
necessary, as I wrote above you can also make it use your
working .config. That's what I do, and it also gives me the initramfs I
need, without having to think about how it does that. I suggest you just
try it, and I'd say there is a really good chance it just works. When you
use 'genkernel --install kernel', you should get the same kernel as when
you build it manually, just with a different name. With 'genkernel
--install all', you also get the initramfs.
I can't guarantee this, though, and especially you seem to have a history
of being bitten by bugs. But then, that's what people say about me, too,
and I'm using genkernel just fine.

Uh. So you think about leaving Gentopo, because your root partition is
barely over half full, and moving /usr somewhere else might involve an
initramfs soon? I'd just wait until it starts getting to 80-90%, and
think about it again.
