    Then _get rid of your init.d_.

    SysV init sequence is insane.

    I use daemontools-based setup and it starts up to login prompt
    in 5-10 secs (counting from the root fs mount).

    In my setup, after a few simple startup scripts a svscan process
    is called, which starts all services in parallel.
    Gettys are services, and start right away.
