# With an emulator booted and accessible via ADB, usage:
# ./build.py avd_patch path/to/booted/avd-image/ramdisk.img
#
# The purpose of this script is to patch AVD ramdisk.img and do a
# full integration test of magiskinit under several circumstances.
# After patching ramdisk.img, close the emulator, then select
# "Cold Boot Now" in AVD Manager to force a full reboot.
#

# P.S. If running against the API 28 image, modify init.hpp and set
# ENABLE_AVD_HACK to 1 to enable special hacks designed specifically
# for this use case.
