# MORESPACE - init script to use an ext4-formatted sdcard for both app installations and user data
# Revision: 3
# Author: github.com/elieux
# Device: Huawei Ascend G300 [U8815] with CM11
#
# Warning: The script does not reformat your sdcard. That needs to be done manually before installing the script.
# Warning: The script is not designed for multiple-partition sdcards (sd-ext).
#
# These directories should be in the root of the card (missing ones are created on the first run):
# - sdcard: user data (e.g. "Android" directory)
# - app: *.apk
# - app-lib: *.so
# - dalvik-cache: *.dex
#
# Other directories are ignored. The root of the card can be accessed through /mnt/real-sdcard0. The original contents of data partition can be accessed through /mnt/real-data.
#
# Installation in recovery:
# adb shell "mount /dev/block/mmcblk0p12 /system" # or mount system in recovery menu
# adb push 10morespace /system/etc/init.d/10morespace
# adb shell "chmod go-w /system/etc/init.d/10morespace"
# adb shell "chmod +x /system/etc/init.d/10morespace"
#
# Copy the contents of app and app-lib to the new locations and reboot. You should see that "apps are being optimized". After you verify it's working, you can delete contents of original app, app-lib and dalvik-cache to free up space.
