What problem does it solve?

Initrd repack and guest-binary management for Capsem during boot setup, enabling fast iteration and deterministic boot behavior by ensuring the correct binaries are loaded from initrd versus rootfs.

Core Features & Use Cases

  • Initrd-first boot: prioritize initrd-bundled binaries (e.g., capsem-init, capsem-net-proxy) over rootfs copies to accelerate boot.
  • Binary lifecycle: coordinate cross-compilation, packaging, and placement of guest binaries when updating the guest toolset.
  • Clear guidance: explain which binaries are injected at boot and which are baked into the rootfs, with a fast feedback loop for testing changes.

Quick Start

Run just run to repack the initrd and update the guest binaries before the next boot.
