    so just to state the obvious: this code is not needed to boot fast.
    It is mostly a workaround for having a bad initrd; if you don't use an
    initrd, or if you use an initrd that's made with the right device nodes
    in it already, you really just don't need this.

    I would much rather that you just fix your initrd... than to put this
    sort of thing into the kernel....
