busybox1.15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：
arm-none-linux-gnueabi/libc/armv4t/usr/lib/目录下的以下内容：
ld-2.8.so // 装在器：运行时加载动态链接库

8. tslib:
/usr/local/tslib/bin:
ts_calibrate
ts_harvest
ts_print
ts_print_raw
ts_test
/usr/local/tslib/etc
ts.conf
