The ab and vndklite designations refer to the underlying architecture of the device’s partitions and software interfaces. An AB partition scheme allows for seamless updates by having two sets of partitions, while vndklite indicates a specific modification to the Vendor Native Development Kit. This modification is designed to allow the GSI to run on devices that have specific filesystem constraints, particularly those where the vendor partition is not easily compatible with standard GSIs. By using a light version of the VNDK, the image gains broader compatibility across different manufacturers.
roar: This is the Build Name or Codename. "Roar" is commonly associated with Project Blaze, a popular custom Android distribution based on AOSP (Android Open Source Project). It suggests this is a custom ROM focused on performance and customization. system-roar-arm64-ab-vndklite-gapps.img.xz

Alex pried open the archive. XZ decompressed into an IMG and then into a filesystem so lean it might have been whittled by a monk: arm64 architecture, A/B partitioning, vndklite to keep the vendor components polite, and gapps bundled neatly for convenience. It was a balance between purity and practicality—freedom without starvation. The ab and vndklite designations refer to the
: A "lightweight" version of the Vendor Native Development Kit. This version is often required for devices where the standard system partition is read-only or has specific size constraints, allowing for easier mounting and modifications. : This version comes pre-installed with Google Apps Standard GSI: Puts VNDK libraries in the System partition
roarThis is the branding or variant name. "Roar" typically refers to a specific build flavor created by a developer (often a personalized or optimized build). In the GSI community, "Roar" builds are known for:
ARM64 Architecture: Specifically built for 64-bit ARM processors, ensuring compatibility with modern hardware.
