Following the guide Signing Builds for Release
<https://source.android.com/devices/tech/ota/sign_builds.html>, I'm trying
to sign a target file with my own keys, I ran the command below:
./build/tools/releasetools/sign_target_files_apks \
-o \
-d ~/.android-certs \
target_files-20161102.zip \
signed-target_files-20161102.zip
failed with:
creating system.img...

It seems like I don't have access permission to
/tmp/targetfiles-wqUF1M/BOOT/RAMDISK/file_contexts,
chown -R myron:myron /tmp didn't solve the problem.
Does anyone know what went wrong? Any help would be appreciated.
