[kpw] 換屏保

# 掛載系統可寫

mntroot rw
# 備份自帶的屏保
mv /usr/share/blanket/screensaver /usr/share/blanket/screensaver.bak
# 將屏保目錄軟鏈接到自定義目錄
ln -s /mnt/us/screensaver /usr/share/blanket/screensaver
# 重新掛載文件系統爲只讀
mntroot ro

刪除時用rm即可：rm /usr/share/blanket/screensaver

刪掉的只是軟鏈接，原來的備份不受影響。

注：爲了方便在Kindle上隨時更換屏保，我寫了一個腳本：

# An easier way to change screen saver
#
# Usage scenario:
#   1. SSH via remote terminal (PC, Mac)
#   2. kterm in Kindle
# Usage:
#   ./css.sh hollywood

OLD=/usr/share/blanket/screensaver
BAK=/usr/share/blanket/screensaver_bak
NEW=/mnt/us/screensaver

# check parameter's existence
if [ ! -d "$1" ];then
	exit 1
fi

# link my image folder
if [ -d "$OLD" ];then
	mntroot rw
	if [ -L "$OLD" ];then
		rm $OLD
	else
		mv $OLD $BAK
	fi
	ln -s $NEW/$1 $OLD
	mntroot ro
fi
