I see. So that's why they "init u". I didn't think about it.

I think most embedded systems nowadays use initramfs. At least that's
what I do, but I don't use x86, only arm and the like. There, you
don't upgrade packaged but the whole system (they call it "firmware
upgrade"). I prefer to upgrade in parts: /usr is external (flash) and
done file-by-file, while / is initramfs and is erased and rewritten
as a whole.

Unfortunately, I don't think it's trivial to split an hda1 install
into an initramfs + external /usr .
