We resolve available partitions for sepolicy.rules when patching boot and bind mount the partition by magiskinit. For older devices, the previous logic won't work because the part name is never readable. Co-authored-by: topjohnwu <topjohnwu@gmail.com>

# AVD MagiskInit Setup
|
|
#####################################################################
|
|
#
|
|
# Support API level: 23 - 33 (21 and 22 images do not have SELinux)
|
|
#
|
|
# 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.
|
|
