一、实现编译时执行对此文件的拷贝。
执行文件存放路径： android/device/hisilicon/bigfish/etc/
目标地址为：/system/etc/
目录：/home/nova/hisi/android/device/hisilicon/Hi3751V811/device_copyfile.mk
#hisi start boot
PRODUCT_COPY_FILES += \
device/hisilicon/bigfish/etc/fstab.bigfish.androido:vendor/etc/fstab.$(TARGET_BOARD_PLATFORM) \
device/hisilicon/bigfish/etc/init.hidolphin.rc:root/init.hidolphin.rc \
device/hisilicon/bigfish/etc/init.bigfish.rc:root/init.$(TARGET_BOARD_PLATFORM).rc \
device/hisilicon/bigfish/etc/ueventd.bigfish.rc:root/ueventd.$(TARGET_BOARD_PLATFORM).rc
我们可以加一条
PRODUCT_COPY_FILES += \
device/hisilicon/bigfish/etc/*.sh:/system/etc/
这样，Android在执行编译的时候就会把新增文件拷贝至相应的目标路径去了，拷贝动作已经实现。
二、添加启动动作，使Android在启动时候执行。
目录：android/device/hisilicon/bigfish/etc/init.bigfish.rc
以memcserver为例：
# Add memcserver
service memcserver /vendor/bin/memcserver
class main
user root
group root
oneshot
三、挂载权限
目录：android/system/core/libcutils/fs_config.c
static const struct fs_path_config android_files[] = {
/* clang-format off */
{ 00644, AID_SYSTEM, AID_SYSTEM, 0, "data/app/*" },
{ 00644, AID_SYSTEM, AID_SYSTEM, 0, "data/app-ephemeral/*" },
{ 00644, AID_SYSTEM, AID_SYSTEM, 0, "data/app-private/*" },
{ 00644, AID_APP, AID_APP, 0, "data/data/*" },
{ 00644, AID_MEDIA_RW, AID_MEDIA_RW, 0, "data/media/*" },
{ 00640, AID_ROOT, AID_SHELL, 0, "data/nativetest/tests.txt" },
{ 00640, AID_ROOT, AID_SHELL, 0, "data/nativetest64/tests.txt" },
...
{ 00550, AID_ROOT, AID_SHELL, 0, "system/etc/init.goldfish.sh" },
{ 00550, AID_ROOT, AID_SHELL, 0, "system/etc/init.ril" },
{ 00555, AID_ROOT, AID_ROOT, 0, "system/etc/ppp/*" },
{ 00555, AID_ROOT, AID_ROOT, 0, "system/etc/rc.*" },
}
