Moving system_other key into product.img
Currently system_other AVB public key is placed in system.img.
However, this makes it's harder to have a *generic* system.img
across different product configs. Moving the key to /product
partition to allow more product-specific AVB keys.
Device board config can add /product/etc/fstab.postinstall,
to mount system_other with this key in /product. It can specify
different mount options, file systems, verity settings, etc., in
this product-specific fstab as well.
Bug: 123611926
Test: `make productimage` checks the following is generated.
$OUT/product/etc/security/avb/system_other.avbpubkey
Also checks it's included in $OUT/installed-files-product.{json, txt}
Test: run the following command and checks that
PRODUCT/etc/security/avb/system_other.avbpubkey is updated:
./build/tools/releasetools/sign_target_files_apks \
--avb_system_other_algorithm SHA256_RSA2048 \
--avb_system_other_key external/avb/test/data/testkey_rsa2048.pem \
out/dist/*-target_files-*.zip signed-target_files.zip

This is the Makefile-based portion of the Android Build System.
For documentation on how to run a build, see Usage.txt
For a list of behavioral changes useful for Android.mk writers see Changes.md
For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.
This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
