Emulator does not start with provided config.ini

🐛 Bug Report

Operating System: Ubuntu 18.04.4 LTS (GNU/Linux 5.3.0-46-generic x86_64)

Docker Image: budtmo/docker-android-x86-9.0

Docker Version:
19.03.8, build afacb8b7f0

Docker-compose version (Only if you use it):
N/A

Docker Command to start docker-android:
docker run -ti --privileged -p 6080:6080 -p 5554:5554 -p 5555:5555 -e DEVICE="Nexus 6p" -e EMULATOR_ARGS="-partition-size 2048" --name android-container 8c1d688c8918 /bin/bash

Expected Behavior

I run the following bash script

adb wait-for-device shell 'while [[ -z $(getprop sys.boot_completed) ]]; do sleep 1; done'

mkdir -p /root/.android/avd
ln -s /root/android_emulator /root/.android/avd/nexus_6p_9.0.avd

echo '
hw.lcd.width=1080
hw.lcd.height=1920
hw.ramSize=4096
vm.heapSize=576
hw.gps=no
hw.accelerometer=no

hw.audioOutput=no
hw.battery=no
disk.dataPartition.size=2048M
hw.mainKeys=true' >> /root/.android/avd/nexus_6p_9.0.avd/config.ini

Here the log

Using Emulator

[539] [ INFO] app - Skin was added in config.ini

[539] [ INFO] app - Emulator was not previously initialized. Preparing a new one...

As shown in the log, because it can't find the /root/android_emulator/config.ini it is Preparing a new one

The latter command produces the following config.ini file:

avd.ini.encoding=UTF-8
abi.type=x86
hw.accelerometer=yes
hw.audioInput=yes
hw.battery=yes
hw.cpu.arch=x86

hw.accelerometer=no

hw.audioOutput=no
hw.battery=no
disk.dataPartition.size=2048M
hw.mainKeys=true

Actual Behavior

If I copy the above config.ini file into the /root/android_emulator/ directory and just restart the script below

adb wait-for-device shell 'while [[ -z $(getprop sys.boot_completed) ]]; do sleep 1; done'

mkdir -p /root/.android/avd
ln -s /root/android_emulator /root/.android/avd/nexus_6p_9.0.avd

the emulator won't start and hangs with the log Using previously initialized AVD...
