usybox1.15制作根文件系统：

1. 配置：

make defconfig

make menucofnig

进行裁剪：

修改Build Option如下：

                   [*] Build BusyBox as a static binary (no shared libs)               

                            [ ] Build shared libbusybox                                         

                            [*] Build with Large File Support (for accessing files > 2 GB)      

                            [*] Do you want to build BusyBox with a Cross Compiler?             

                            (/usr/local/arm/4.3.2/bin/arm-linux-) Cross Compiler prefix         

                            [ ] Compile all sources at once 

修改Installation Options如下：

[*] Don't use /usr   

Applets links (as soft-links)  --->                  

(../rootfs) BusyBox installation prefix 

修改Shell，选择默认的shell为ash，必须的呀。 Choose your default shell (ash)  --->

make ; make installation

2. 建立目录：

cd ../rootfs

mkdir dev usr etc proc sys var home root tmp lib mnt usr

mknod dev/console c 5 1

3. etc/fstab 内容：

proc            /proc   proc    defaults        0       0

tmpfs           /tmp    tmpfs   defaults        0       0

sysfs           /sys    sysfs   defaults        0       0

4. etc/init.d/rcS内容：

#! /bin/sh

/bin/mount -a

/sbin/mdev -s

5. etc/inittab内容

::sysinit:/etc/init.d/rcS

::respawn:-/bin/sh

tty2::askfirst:-/bin/sh

::ctrlaltdel:/bin/umount -a -r

6. etc/profile内容：

alias ll="ls -l"                  

PATH=/bin:/sbin:/usr/bin:/usr/sbin

export PATH        

cd /root

#可将第9步的环境变量放在这个文件里面

7. 拷贝/lib内容：

拷贝4.3.2/arm-none-linux-gnueabi/libc/armv4t/lib/或目录下的以下内容：
