现在手机的开关机过程比较慢长，为了不至于让用户等得不耐烦，为了避免用户在不耐烦时做些误操作，也为了美观，手机在开关机时显示动画已经成为惯例了。最近要做Linux手机开关机动画，花了点时间去研究Bootsplash，这里做个笔记。

1. 下载软件包。
http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.21.tar.bz2
ftp://ftp.bootsplash.org/pub/bootsplash/rpm-sources/bootsplash/bootsplash-3.1.tar.bz2
ftp://ftp.bootsplash.org/pub/bootsplash/kernel/bootsplash-3.1.6-2.6.21.diff.gz
http://www.bootsplash.de/files/themes/Theme-Fedora.tar.bz2
(主题文件可以根据需要下载)

2. 编译内核
tar jxf linux-2.6.21.tar.bz2
gzip -d bootsplash-3.1.6-2.6.21.diff.gz
cd linux-2.6.21
patch -p1 <../bootsplash-3.1.6-2.6.21.diff
make menuconfig
保证下列配置正常
Device Drivers
Graphics support
<*> Support for frame buffer devices
[*] VESA VGA graphics support
Console display driver support
<*> Framebuffer Console support
Bootsplash configuration
[*] Bootup splash screen
make; make modules_install;make install

3. 编译工具
tar jxvf bootsplash-3.1.tar.bz2
cd bootsplash-3.1/Utilities
make
(编译mng.c时，会成现几个编译错误，手工修改过来)
cp fbresolution fbmngplay fbtruetype splash splashpbm /sbin
splash -s –f /etc/bootsplash/themes/Fedora/config/bootsplash-1024x768.cfg>/boot/bootsplash
cd ../Scripts/
cp * /etc/rc.d

4. 生成主题数据文件
mkdir -p /etc/bootsplash/themes
tar jxvf Theme-Fedora.tar.bz2 -C /etc/bootsplash/themes/

5. 生成initrd
mkdir temp
cd temp
cp /boot/initrd-2.6.21.img ../initrd.gz
gzip -d ../initrd.gz
cpio -i <../initrd
cp /boot/bootsplash .
find . | cpio -c -o > ../initrd-2.6.21-splash.img
gzip ../initrd-2.6.21-splash.img
cp ../initrd-2.6.21-splash.img.gz /boot/initrd-2.6.21-splash.img

6. 增加grub menu配置文件
title Fedora Core (2.6.21) splash
root (hd0,6)
kernel /boot/vmlinuz-2.6.21 ro root=LABEL=/ vga=0x317 splash=silent
initrd /boot/initrd-2.6.21-splash.img

7. 修改splash.sh
把THEME修改为实际的主题名。
THEME="No bootsplash theme selected"
à
THEME="Fedora"

8. 修改/etc/rc.d/rc
l 先做个备份：
cd /etc/rc.d/
cp rc rc.bak

(蓝色部分为新增脚本)
l 声明splash.sh中需要变量。

# check a file to be a correct runlevel script check_runlevel () { # Check if the file exists at all. [ -x "$1" ] || return 1 is_ignored_file "$1" && return 1 return 0 } export progress=0 export sscripts=0 export kscripts=0 for item in /etc/rc.d/rc3.d/S*;do sscripts=$(($sscripts + 1)) done for item in /etc/rc.d/rc3.d/K*;do kscripts=$(($sscripts + 1)) done

l 设置关机进度条。

# First, run the KILL scripts. for i in /etc/rc$runlevel.d/K* ; do check_runlevel "$i" || continue # Check if the subsystem is already up. subsys=${i#/etc/rc$runlevel.d/K??} [ -f /var/lock/subsys/$subsys -o -f /var/lock/subsys/$subsys.init ] / || continue # Bring the subsystem down. if LC_ALL=C egrep -q "^..*init.d/functions" $i ; then $i stop else action $"Stopping $subsys: " $i stop fi progress=$(($progress+ 1)) /etc/rc.d/splash.sh 2>/dev/nul done

l 设置开机进度条。

# Now run the START scripts. for i in /etc/rc$runlevel.d/S* ; do check_runlevel "$i" || continue # Check if the subsystem is already up. subsys=${i#/etc/rc$runlevel.d/S??} [ -f /var/lock/subsys/$subsys -o -f /var/lock/subsys/$subsys.init ] / && continue # If we're in confirmation mode, get user confirmation if [ -f /var/run/confirm ]; then confirm $subsys test $? = 1 && continue fi update_boot_stage "$subsys" # Bring the subsystem up. if [ "$subsys" = "halt" -o "$subsys" = "reboot" ]; then export LC_ALL=C exec $i start fi if LC_ALL=C egrep -q "^..*init.d/functions" $i / || [ "$subsys" = "single" -o "$subsys" = "local" ]; then $i start else action $"Starting $subsys: " $i start fi progress=$(($progress+ 1)) /etc/rc.d/splash.sh 2>/dev/nul done

重新起动就OK了。

(测试环境：Fedora Core release 6 (Zod))
