自動掛載SD

由於新的filesystem源碼使用vold作為SD卡自動掛載程式，而舊的使用mountd程式來掛載。下面介紹如何使用mountd來掛載SD卡。

1.對system/core/rootdir/init.rc檔做如下修改。把vold程式遮罩，打開mountd

#service vold /system/bin/vold

# socket vold stream 0660 root mount

service mountd /system/bin/mountd

socket mountd stream 0660 root mount

2.在system/core/rootdir/Android.mk添加mountd.conf配置檔.

copy_from := \

etc/mountd.conf \

etc/dbus.conf \

etc/init.goldfish.sh \

etc/hosts

3. 打開mountd的編譯選項，對system\core\mountd\Android.mk檔做如下修改

LOCAL_PATH:= $(call my-dir)

include $(CLEAR_VARS)

LOCAL_SRC_FILES:= \

AutoMount.c \

ProcessKiller.c \

Server.c \

mountd.c \

ASEC.c \

logwrapper.c

LOCAL_MODULE:= mountd

LOCAL_C_INCLUDES := $(KERNEL_HEADERS)

LOCAL_CFLAGS := -DCREATE_MOUNT_POINTS=0

LOCAL_SHARED_LIBRARIES := libcutils

include $(BUILD_EXECUTABLE)
