The table below lists the remaining parts of the project:

Component	Type	Description
packaging	infrastructure	Scripts and metadata for producing packaged binaries (components, hypervisors, kernel and rootfs).
kernel	kernel	Linux kernel used by the hypervisor to boot the guest image. Patches are stored here.
osbuilder	infrastructure	Tool to create "mini O/S" rootfs and initrd images and kernel for the hypervisor.
agent-ctl	utility	Tool that provides low-level access for testing the agent.
trace-forwarder	utility	Agent tracing helper.
