The Android Chroot Experiment We Never Shipped

After successfully moving to Android-x86, the Edge security team attempted to further optimize by running both the fuzzer and the browser on a single VM using a Debian chroot. This "Single-VM" model ultimately failed due to "Linker Hell" between Bionic and glibc, alongside conflicting filesystem permission models. Additionally, unreliable bootloader logic and partition drift made automating kernel arguments at cloud scale too risky for production. Ultimately, the team determined that the engineering effort required to bypass these deep-level technical blockers outweighed the potential cost savings.
