FAOD, these are my init.S steps:
   /etc/rcS.d:
    S02banner.sh -> ../init.d/banner.sh
    S03sysfs.sh -> ../init.d/sysfs.sh
    S04udev -> ../init.d/udev
    S10checkroot.sh -> ../init.d/checkroot.sh
    S20modutils.sh -> ../init.d/modutils.sh
    S35mountall.sh -> ../init.d/mountall.sh
    S36udev-cache -> ../init.d/udev-cache
    S37populate-volatile.sh -> ../init.d/populate-volatile.sh
    S38devpts.sh -> ../init.d/devpts.sh
    S39hostname.sh -> ../init.d/hostname.sh
    S40networking -> ../init.d/networking
    S41nat_setup -> ../init.d/nat_setup
    S45mountnfs.sh -> ../init.d/mountnfs.sh
    S50dhcp-server -> ../init.d/dhcp-server
    S55bootmisc.sh -> ../init.d/bootmisc.sh
