[Linux] Auto mount 自動掛載 usb disk & SD card

1. /etc/mdev.conf 加入

sd[a-z][0-9] 0:0 600 *(/etc/init.d/automount.sh $MDEV &)

mmcblk0p[0-9] 0:0 600 *(/etc/init.d/automount.sh $MDEV &)

2. 創建/etc/init.d/automount.sh

#!/bin/sh
MOUNT_PATH=""
MSG_PATH="/dev/ttyS0"

if [ $1 == "" ]; then
    echo "[AutoMount] automount.sh parameter is none" > $MSG_PATH
    exit 0
elif [ $1 == "mmcblk0p1" ]; then
    MOUNT_PATH="/mnt/sdcard"
else
    name=$1
    check=${name%[1-9]}
    vendor=`cat /sys/block/$check/device/vendor`
    if [ $vendor == "ATA" ]; then
       MOUNT_PATH="/mnt/hdd/"$name
    else
       MOUNT_PATH="/mnt/usb/"$name
    fi   
fi
echo "[AutoMount] mount path : $MOUNT_PATH" >> $MSG_PATH

FORMAT=`/sbin/fdisk -l | grep $1`
OLD_MOUNT_PATH=`mount | grep $MOUNT_PATH`

if [ "$OLD_MOUNT_PATH" == "" ]; then

    if [ ! -x $MOUNT_PATH ]; then
        mkdir -p $MOUNT_PATH
    fi 

    for token in $FORMAT
    do
        if [ $token == "FAT32" ]; then
            mount -t vfat /dev/$1 $MOUNT_PATH
            echo "[AutoMount] mount -t vfat /dev/$1 $MOUNT_PATH" > $MSG_PATH
        elif [ $token == "FAT16" ]; then
            mount -t vfat /dev/$1 $MOUNT_PATH

                export LD_LIBRARY_PATH=/lib/:${LD_LIBRARY_PATH}
                /usr/app/ntfs-3g /dev/$1 $MOUNT_PATH
                echo "[AutoMount] /usr/app/ntfs-3g /dev/$1 $MOUNT_PATH" > $MSG_PATH

                echo "[AutoMount] mount /dev/$1 $MOUNT_PATH" > $MSG_PATH
        fi
