Write aliases before ffs mount in recovery

This is necessary to support kernel changes
that allow for multiple ffs functions. Some
kernels require aliases in order to name
function instances before mount time.

Test: Reboot into recovery, verify adb works

The Recovery Image

Quick turn-around testing

mm -j && m ramdisk-nodeps && m recoveryimage-nodeps

# To boot into the new recovery image
# without flashing the recovery partition:
adb reboot bootloader
fastboot boot $ANDROID_PRODUCT_OUT/recovery.img

Running the tests

# After setting up environment and lunch.
mmma -j bootable/recovery

# Running the tests on device.
adb root
adb sync data

# 32-bit device
adb shell /data/nativetest/recovery_unit_test/recovery_unit_test
adb shell /data/nativetest/recovery_component_test/recovery_component_test

# Or 64-bit device
adb shell /data/nativetest64/recovery_unit_test/recovery_unit_test
adb shell /data/nativetest64/recovery_component_test/recovery_component_test

Running the manual tests

recovery-refresh and recovery-persist executables exist only on systems without /cache partition. And we need to follow special steps to run tests for them.

  • Execute the test on an A/B device first. The test should fail but it will log some contents to pmsg.

  • Reboot the device immediately and run the test again. The test should save the contents of pmsg buffer into /data/misc/recovery/inject.txt. Test will pass if this file has expected contents.
