[kpw] 换屏保

# 挂载系统可写

mntroot rw
# 备份自带的屏保
mv /usr/share/blanket/screensaver /usr/share/blanket/screensaver.bak
# 将屏保目录软链接到自定义目录
ln -s /mnt/us/screensaver /usr/share/blanket/screensaver
# 重新挂载文件系统为只读
mntroot ro

删除时用rm即可：rm /usr/share/blanket/screensaver

删掉的只是软链接，原来的备份不受影响。

注：为了方便在Kindle上随时更换屏保，我写了一个脚本：
