在etc/rc.d/rcS.d目录下增加一个启动文件，如S91startuserp：
root@EPC-8900:/etc/rc.d/rcS.d# cat S91startuserp
#! /bin/sh
# chkconfig: S 91 0
# Init script information
INIT_NAME=startuserp
# Load init script configuration
[ -f /etc/default/$INIT_NAME ] && . /etc/default/$INIT_NAME
# Source the init script functions
. /etc/init.d/init-functions
RET=0 ERROR=""
cat /etc/hostname > /proc/sys/kernel/hostname
#echo "################## S91S91S91"
#/root/startuserp
echo "ssh-server: start sshd"
mknod /dev/random c 1 8 > /dev/null 2>&1
